Architecture is both the process and the product of planning, designing, and constructing buildings or any other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.
Architecture (Latin architectura, from the Greek ἀρχιτέκτων arkhitekton "architect", from ἀρχι- "chief" and τέκτων "creator") is both the process and the product of planning, designing, and constructing buildings and other physical structures.
Architecture can mean:
The earliest surviving written work on the subject of architecture is De architectura, by the Roman architect Vitruvius in the early 1st century AD. According to Vitruvius, a good building should satisfy the three principles of firmitas, utilitas, venustas, commonly known by the original translation – firmness, commodity and delight. An equivalent in modern English would be:
According to Vitruvius, the architect should strive to fulfill each of these three attributes as well as possible. Leon Battista Alberti, who elaborates on the ideas of Vitruvius in his treatise, De Re Aedificatoria, saw beauty primarily as a matter of proportion, although ornament also played a part. For Alberti, the rules of proportion were those that governed the idealised human figure, the Golden mean.
The most important aspect of beauty was, therefore, an inherent part of an object, rather than something applied superficially, and was based on universal, recognisable truths. The notion of style in the arts was not developed until the 16th century, with the writing of Vasari: by the 18th century, his Lives of the Most Excellent Painters, Sculptors, and Architects had been translated into Italian, French, Spanish, and English.
In the early 19th century, Augustus Welby Northmore Pugin wrote Contrasts (1836) that, as the titled suggested, contrasted the modern, industrial world, which he disparaged, with an idealized image of neo-medieval world. Gothic architecture, Pugin believed, was the only "true Christian form of architecture."
The 19th-century English art critic, John Ruskin, in his Seven Lamps of Architecture, published 1849, was much narrower in his view of what constituted architecture. Architecture was the "art which so disposes and adorns the edifices raised by men ... that the sight of them" contributes "to his mental health, power, and pleasure".
For Ruskin, the aesthetic was of overriding significance. His work goes on to state that a building is not truly a work of architecture unless it is in some way "adorned". For Ruskin, a well-constructed, well-proportioned, functional building needed string courses or rustication, at the very least.
On the difference between the ideals of architecture and mere construction, the renowned 20th-century architect Le Corbusier wrote: "You employ stone, wood, and concrete, and with these materials you build houses and palaces: that is construction. Ingenuity is at work. But suddenly you touch my heart, you do me good. I am happy and I say: This is beautiful. That is Architecture".
While the notion that structural and aesthetic considerations should be entirely subject to functionality was met with both popularity and skepticism, it had the effect of introducing the concept of "function" in place of Vitruvius' "utility". "Function" came to be seen as encompassing all criteria of the use, perception and enjoyment of a building, not only practical but also aesthetic, psychological and cultural.
Nunzia Rondanini stated, "Through its aesthetic dimension architecture goes beyond the functional aspects that it has in common with other human sciences. Through its own particular way of expressing values, architecture can stimulate and influence social life without presuming that, in and of itself, it will promote social development.'
To restrict the meaning of (architectural) formalism to art for art's sake is not only reactionary; it can also be a purposeless quest for perfection or originality which degrades form into a mere instrumentality".
In the late 20th century a new concept was added to those included in the compass of both structure and function, the consideration of sustainability, hence sustainable architecture. To satisfy the contemporary ethos a building should be constructed in a manner which is environmentally friendly in terms of the production of its materials, its impact upon the natural and built environment of its surrounding area and the demands that it makes upon non-sustainable power sources for heating, cooling, water and waste management and lighting.
Plato to Michel Foucault, Gilles Deleuze, Robert Venturi as well as many other philosophers and theoreticians, distinguish architecture ('technion') from building ('demiorgos'), attributing the former to mental traits, and the latter to the divine or natural.
The Wittgenstein House is considered one of the most important examples of interactions between philosophy and architecture. Built by renowned Austrian philosopher Ludwig Wittgenstein, the house has been the subject of extensive research about the relationship between its stylistic features, Wittgenstein's personality, and his philosophy.
Building first evolved out of the dynamics between needs (shelter, security, worship, etc.) and means (available building materials and attendant skills). As human cultures developed and knowledge began to be formalized through oral traditions and practices, building became a craft, and "architecture" is the name given to the most highly formalized and respected versions of that craft. It is widely assumed that architectural success was the product of a process of trial and error, with progressively less trial and more replication as the results of the process proved increasingly satisfactory. What is termed vernacular architecture continues to be produced in many parts of the world. Indeed, vernacular buildings make up most of the built world that people experience every day. Early human settlements were mostly rural. Due to a surplus in production the economy began to expand resulting in urbanization thus creating urban areas which grew and evolved very rapidly in some cases, such as that of Çatal Höyük in Anatolia and Mohenjo Daro of the Indus Valley Civilization in modern-day Pakistan.
Neolithic settlements and "cities" include:
In many ancient civilizations, such as those of Egypt and Mesopotamia, architecture and urbanism reflected the constant engagement with the divine and the supernatural, and many ancient cultures resorted to monumentality in architecture to represent symbolically the political power of the ruler, the ruling elite, or the state itself.
The architecture and urbanism of the Classical civilizations such as the Greek and the Roman evolved from civic ideals rather than religious or empirical ones and new building types emerged. Architectural "style" developed in the form of the Classical orders. Roman architecture was influenced by Greek architecture as they incorporated many Greek elements into their building practices.
Texts on architecture have been written since ancient time. These texts provided both general advice and specific formal prescriptions or canons. Some examples of canons are found in the writings of the 1st-century BCE Roman Architect Vitruvius. Some of the most important early examples of canonic architecture are religious.
Early Asian writings on architecture include the Kao Gong Ji of China from the 7th–5th centuries BCE; the Shilpa Shastras of ancient India; Manjusri Vasthu Vidya Sastra of Sri Lanka and Araniko of Nepal .
The architecture of different parts of Asia developed along different lines from that of Europe; Buddhist, Hindu and Sikh architecture each having different characteristics. Buddhist architecture, in particular, showed great regional diversity. Hindu temple architecture, which developed around the 3rd century BCE, is governed by concepts laid down in the Shastras, and is concerned with expressing the macrocosm and the microcosm. In many Asian countries, pantheistic religion led to architectural forms that were designed specifically to enhance the natural landscape.
Islamic architecture began in the 7th century CE, incorporating architectural forms from the ancient Middle East and Byzantium, but also developing features to suit the religious and social needs of the society. Examples can be found throughout the Middle East, North Africa, Spain and the Indian Sub-continent.
In Europe during the Medieval period, guilds were formed by craftsmen to organize their trades and written contracts have survived, particularly in relation to ecclesiastical buildings. The role of architect was usually one with that of master mason, or Magister lathomorum as they are sometimes described in contemporary documents.
The major architectural undertakings were the buildings of abbeys and cathedrals. From about 900 CE onward, the movements of both clerics and tradesmen carried architectural knowledge across Europe, resulting in the pan-European styles Romanesque and Gothic.
Also, significant part of Middle Ages architectural heritage are numerous fortifications across the continent. From Balkans to Spain, and from Malta to Estonia, these buildings represent important part of European heritage.
The Late Middle Ages in Central and Southeastern Europe also saw the expansion of Ottoman architecture, which spread alongside the Ottoman Empire, from Anatolia via the Balkans, to Central and Eastern Europe and beyond to the northern shores of the Black Sea. In regions from which the Ottoman Empire would eventually be forced to retreat, almost all their architectural designs were destroyed. In the 21st century, the only significant architectural heritage on European soil outside of modern-day Turkey, can be found in Bosnia and Herzegovina, Kosovo, and Albania, while some remnants can be found in the Muslim-inhabited parts of Serbia, Montenegro, Macedonia and Bulgaria.
In Renaissance Europe, from about 1400 onwards, there was a revival of Classical learning accompanied by the development of Renaissance Humanism which placed greater emphasis on the role of the individual in society than had been the case during the Medieval period. Buildings were ascribed to specific architects – Brunelleschi, Alberti, Michelangelo, Palladio – and the cult of the individual had begun. There was still no dividing line between artist, architect and engineer, or any of the related vocations, and the appellation was often one of regional preference.
A revival of the Classical style in architecture was accompanied by a burgeoning of science and engineering which affected the proportions and structure of buildings. At this stage, it was still possible for an artist to design a bridge as the level of structural calculations involved was within the scope of the generalist.
With the emerging knowledge in scientific fields and the rise of new materials and technology, architecture and engineering began to separate, and the architect began to concentrate on aesthetics and the humanist aspects, often at the expense of technical aspects of building design. There was also the rise of the "gentleman architect" who usually dealt with wealthy clients and concentrated predominantly on visual qualities derived usually from historical prototypes, typified by the many country houses of Great Britain that were created in the Neo Gothic or Scottish Baronial styles. Formal architectural training in the 19th century, for example at École des Beaux-Arts in France, gave much emphasis to the production of beautiful drawings and little to context and feasibility.
Meanwhile, the Industrial Revolution laid open the door for mass production and consumption. Aesthetics became a criterion for the middle class as ornamented products, once within the province of expensive craftsmanship, became cheaper under machine production.
Vernacular architecture became increasingly ornamental. House builders could use current architectural design in their work by combining features found in pattern books and architectural journals.
Around the beginning of the 20th century, a general dissatisfaction with the emphasis on revivalist architecture and elaborate decoration gave rise to many new lines of thought that served as precursors to Modern Architecture. Notable among these is the Deutscher Werkbund, formed in 1907 to produce better quality machine made objects. The rise of the profession of industrial design is usually placed here. Following this lead, the Bauhaus school, founded in Weimar, Germany in 1919, redefined the architectural bounds prior set throughout history, viewing the creation of a building as the ultimate synthesis—the apex—of art, craft, and technology.
When modern architecture was first practiced, it was an avant-garde movement with moral, philosophical, and aesthetic underpinnings. Immediately after World War I, pioneering modernist architects sought to develop a completely new style appropriate for a new post-war social and economic order, focused on meeting the needs of the middle and working classes. They rejected the architectural practice of the academic refinement of historical styles which served the rapidly declining aristocratic order. The approach of the Modernist architects was to reduce buildings to pure forms, removing historical references and ornament in favor of functionalist details. Buildings displayed their functional and structural elements, exposing steel beams and concrete surfaces instead of hiding them behind decorative forms. Architects such as Frank Lloyd Wright developed organic architecture, in which the form was defined by its environment and purpose, with an aim to promote harmony between human habitation and the natural world with prime examples being Robie House and Fallingwater.
Architects such as Mies van der Rohe, Philip Johnson and Marcel Breuer worked to create beauty based on the inherent qualities of building materials and modern construction techniques, trading traditional historic forms for simplified geometric forms, celebrating the new means and methods made possible by the Industrial Revolution, including steel-frame construction, which gave birth to high-rise superstructures. Fazlur Rahman Khan's development of the tube structure was a technological break-through in building ever higher. By mid-century, Modernism had morphed into the International Style, an aesthetic epitomized in many ways by the Twin Towers of New York's World Trade Center designed by Minoru Yamasaki.
Many architects resisted modernism, finding it devoid of the decorative richness of historical styles. As the first generation of modernists began to die after World War II, a second generation of architects including Paul Rudolph, Marcel Breuer, and Eero Saarinen tried to expand the aesthetics of modernism with Brutalism, buildings with expressive sculptural façades made of unfinished concrete. But an even new younger postwar generation critiqued modernism and Brutalism for being too austere, standardized, monotone, and not taking into account the richness of human experience offered in historical buildings across time and in different places and cultures.
One such reaction to the cold aesthetic of modernism and Brutalism is the school of metaphoric architecture, which includes such things as biomorphism and zoomorphic architecture, both using nature as the primary source of inspiration and design. While it is considered by some to be merely an aspect of postmodernism, others consider it to be a school in its own right and a later development of expressionist architecture.
Beginning in the late 1950s and 1960s, architectural phenomenology emerged as an important movement in the early reaction against modernism, with architects like Charles Moore in the United States, Christian Norberg-Schulz in Norway, and Ernesto Nathan Rogers and Vittorio Gregotti, Michele Valori, Bruno Zevi in Italy, who collectively popularized an interest in a new contemporary architecture aimed at expanding human experience using historical buildings as models and precedents. Postmodernism produced a style that combined contemporary building technology and cheap materials, with the aesthetics of older pre-modern and non-modern styles, from high classical architecture to popular or vernacular regional building styles. Robert Venturi famously defined postmodern architecture as a "decorated shed" (an ordinary building which is functionally designed inside and embellished on the outside), and upheld it against modernist and brutalist "ducks" (buildings with unnecessarily expressive tectonic forms).
Since the 1980s, as the complexity of buildings began to increase (in terms of structural systems, services, energy and technologies), the field of architecture became multi-disciplinary with specializations for each project type, technological expertise or project delivery methods. In addition, there has been an increased separation of the 'design' architect [Notes 1] from the 'project' architect who ensures that the project meets the required standards and deals with matters of liability.[Notes 2] The preparatory processes for the design of any large building have become increasingly complicated, and require preliminary studies of such matters as durability, sustainability, quality, money, and compliance with local laws. A large structure can no longer be the design of one person but must be the work of many. Modernism and Postmodernism have been criticised by some members of the architectural profession who feel that successful architecture is not a personal, philosophical, or aesthetic pursuit by individualists; rather it has to consider everyday needs of people and use technology to create liveable environments, with the design process being informed by studies of behavioral, environmental, and social sciences.
Environmental sustainability has become a mainstream issue, with profound effect on the architectural profession. Many developers, those who support the financing of buildings, have become educated to encourage the facilitation of environmentally sustainable design, rather than solutions based primarily on immediate cost. Major examples of this can be found in passive solar building design, greener roof designs, biodegradable materials, and more attention to a structure's energy usage. This major shift in architecture has also changed architecture schools to focus more on the environment. There has been an acceleration in the number of buildings which seek to meet green building sustainable design principles. Sustainable practices that were at the core of vernacular architecture increasingly provide inspiration for environmentally and socially sustainable contemporary techniques. The U.S. Green Building Council's LEED (Leadership in Energy and Environmental Design) rating system has been instrumental in this.
Concurrently, the recent movements of New Urbanism, metaphoric architecture and New Classical Architecture promote a sustainable approach towards construction that appreciates and develops smart growth, architectural tradition and classical design. This in contrast to modernist and globally uniform architecture, as well as leaning against solitary housing estates and suburban sprawl. Glass curtain walls, which were the hallmark of the ultra modern urban life in many countries surfaced even in developing countries like Nigeria where international styles had been represented since the mid 20th Century mostly because of the leanings of foreign-trained architects.
Business architecture is defined as "a blueprint of the enterprise that provides a common understanding of the organization and is used to align strategic objectives and tactical demands." People who develop and maintain business architecture are known as business architects.
Cognitive architecture can refer to a theory about the structure of the human mind. One of the main goals of a cognitive architecture is to summarize the various results of cognitive psychology in a comprehensive computer model. However, the results need to be in a formalized form so far that they can be the basis of a computer program. The formalized models can be used to further refine a comprehensive theory of cognition, and more immediately, as a commercially usable model. Successful cognitive architectures include ACT-R (Adaptive Control of Thought, ACT) and SOAR.
The Institute of Creative Technologies defines cognitive architecture as: "hypothesis about the fixed structures that provide a mind, whether in natural or artificial systems, and how they work together – in conjunction with knowledge and skills embodied within the architecture – to yield intelligent behavior in a diversity of complex environments."
In computer engineering, "computer architecture" is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. Some definitions of architecture define it as describing the capabilities and programming model of a computer but not a particular implementation. In other definitions computer architecture involves instruction set architecture design, microarchitecture design, logic design, and implementation.
Enterprise architecture (EA) is "a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a holistic approach at all times, for the successful development and execution of strategy. Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes."
Practitioners of enterprise architecture, enterprise architects, are responsible for performing the analysis of business structure and processes and are often called upon to draw conclusions from the information collected to address the goals of enterprise architecture: effectiveness, efficiency, agility, and durability.
Interior architecture is the design of a space which has been created by structural boundaries and the human interaction within these boundaries. It can also be the initial design and plan for use, then later redesign to accommodate a changed purpose, or a significantly revised design for adaptive reuse of the building shell. The latter is often part of sustainable architecture practices, conserving resources through "recycling" a structure by adaptive redesign. Generally referred to as the spatial art of environmental design, form and practice, interior architecture is the process through which the interiors of buildings are designed, concerned with all aspects of the human uses of structural spaces. Put simply, Interior Architecture is the design of an interior in architectural terms.
Landscape architecture is the design of outdoor public areas, landmarks, and structures to achieve environmental, social-behavioral, or aesthetic outcomes. It involves the systematic investigation of existing social, ecological, and soil conditions and processes in the landscape, and the design of interventions that will produce the desired outcome. The scope of the profession includes landscape design; site planning; stormwater management; environmental restoration; parks and recreation planning; visual resource management; green infrastructure planning and provision; and private estate and residence landscape master planning and design; all at varying scales of design, planning and management. A practitioner in the profession of landscape architecture is called a landscape architect.
Naval architecture, also known as naval engineering, is an engineering discipline dealing with the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. Naval architecture involves basic and applied research, design, development, design evaluation and calculations during all stages of the life of a marine vehicle. Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Ship design calculations are also required for ships being modified (by means of conversion, rebuilding, modernization, or repair). Naval architecture also involves formulation of safety regulations and damage control rules and the approval and certification of ship designs to meet statutory and non-statutory requirements.
Network architecture is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats use. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
Software architecture refers to the fundamental structures of a software system, the discipline of creating such structures, and the documentation of these structures. These structures are needed to reason about the software system. Each structure comprises software elements, relations among them, and properties of both elements and relations, along with rationale for the introduction and configuration of each element. The architecture of a software system is a metaphor, analogous to the architecture of a building.
Software architecture is about making fundamental structural choices which are costly to change once implemented. Software architecture choices, also called architectural decisions, include specific structural options from possibilities in the design of software. For example, the systems that controlled the space shuttle launch vehicle had the requirement of being very fast and very reliable. Therefore, an appropriate real-time computing language would need to be chosen. Additionally, to satisfy the need for reliability the choice could be made to have multiple redundant and independently produced copies of the program, and to run these copies on independent hardware while cross-checking results.
In distributed computing, computations are distributed over different networked computers, which communicate and coordinate their actions by passing messages to one another. Examples of architectures for distributed computing include high-level architecture (HLA) and Distributed Interactive Simulation (DIS).
System architecture is a conceptual model that defines the structure, behavior, and more views of a system. An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
A system architecture can comprise system components that will work together to implement the overall system. There have been efforts to formalize languages to describe system architecture, collectively these are called architecture description languages (ADLs).
Urban design is the process of designing and shaping the physical features of cities, towns and villages. In contrast to architecture, which focuses on the design of individual buildings, urban design deals with the larger scale of groups of buildings, streets and public spaces, whole neighborhoods and districts, and entire cities, with the goal of making urban areas functional, attractive, and sustainable.
Urban design is an inter-disciplinary field that utilizes elements of many built environment professions, including landscape architecture, urban planning, architecture, civil engineering and municipal engineering. It is common for professionals in all these disciplines to practice urban design. In more recent times different sub-subfields of urban design have emerged such as strategic urban design, landscape urbanism, water-sensitive urban design, and sustainable urbanism.
Architecture describes the internal organization of a computer in an abstract way; that is, it defines the capabilities of the computer and its programming model. You can have two computers that have been constructed in different ways with different technologies but with the same architecture.
This task has many aspects, including instruction set design, functional organization, logic design, and implementation.
ARM, previously Advanced RISC Machine, originally Acorn RISC Machine, is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments. Arm Holdings develops the architecture and licenses it to other companies, who design their own products that implement one of those architectures—including systems-on-chips (SoC) and systems-on-modules (SoM) that incorporate memory, interfaces, radios, etc. It also designs cores that implement this instruction set and licenses these designs to a number of companies that incorporate those core designs into their own products.
Processors that have a RISC architecture typically require fewer transistors than those with a complex instruction set computing (CISC) architecture (such as the x86 processors found in most personal computers), which improves cost, power consumption, and heat dissipation. These characteristics are desirable for light, portable, battery-powered devices—including smartphones, laptops and tablet computers, and other embedded systems. For supercomputers, which consume large amounts of electricity, ARM could also be a power-efficient solution.ARM Holdings periodically releases updates to the architecture. Architecture versions ARMv3 to ARMv7 support 32-bit address space (pre-ARMv3 chips, made before ARM Holdings was formed, as used in the Acorn Archimedes, had 26-bit address space) and 32-bit arithmetic; most architectures have 32-bit fixed-length instructions. The Thumb version supports a variable-length instruction set that provides both 32- and 16-bit instructions for improved code density. Some older cores can also provide hardware execution of Java bytecodes. Released in 2011, the ARMv8-A architecture added support for a 64-bit address space and 64-bit arithmetic with its new 32-bit fixed-length instruction set.With over 100 billion ARM processors produced as of 2017, ARM is the most widely used instruction set architecture and the instruction set architecture produced in the largest quantity. Currently, the widely used Cortex cores, older "classic" cores, and specialized SecurCore cores variants are available for each of these to include or exclude optional capabilities.Architect
An architect is a person who plans, designs and reviews the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose. Etymologically, architect derives from the Latin architectus, which derives from the Greek (arkhi-, chief + tekton, builder), i.e., chief builder.Professionally, an architect's decisions affect public safety, and thus an architect must undergo specialized training consisting of advanced education and a practicum (or internship) for practical experience to earn a license to practice architecture. Practical, technical, and academic requirements for becoming an architect vary by jurisdiction.Art Deco
Art Deco, sometimes referred to as Deco, is a style of visual arts, architecture and design that first appeared in France just before World War I. Art Deco influenced the design of buildings, furniture, jewelry, fashion, cars, movie theatres, trains, ocean liners, and everyday objects such as radios and vacuum cleaners. It took its name, short for Arts Décoratifs, from the Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris in 1925. It combined modern styles with fine craftsmanship and rich materials. During its heyday, Art Deco represented luxury, glamour, exuberance, and faith in social and technological progress.
Art Deco was a pastiche of many different styles, sometimes contradictory, united by a desire to be modern. From its outset, Art Deco was influenced by the bold geometric forms of Cubism; the bright colors of Fauvism and of the Ballets Russes; the updated craftsmanship of the furniture of the eras of Louis Philippe I and Louis XVI; and the exotic styles of China and Japan, India, Persia, ancient Egypt and Maya art. It featured rare and expensive materials, such as ebony and ivory, and exquisite craftsmanship. The Chrysler Building and other skyscrapers of New York built during the 1920s and 1930s are monuments of the Art Deco style.
In the 1930s, during the Great Depression, the Art Deco style became more subdued. New materials arrived, including chrome plating, stainless steel, and plastic. A sleeker form of the style, called Streamline Moderne, appeared in the 1930s; it featured curving forms and smooth, polished surfaces. Art Deco is one of the first truly international styles, but its dominance ended with the beginning of World War II and the rise of the strictly functional and unadorned styles of modern architecture and the International Style of architecture that followed.Baroque
The Baroque (UK: , US: ) is a highly ornate and often extravagant style of architecture, music, painting, sculpture and other arts that flourished in Europe from the early 17th until the mid-18th century. It followed the Renaissance style and preceded the Rococo (in the past often referred to as "late Baroque") and Neoclassical styles. It was encouraged by the Catholic Church as a means to counter the simplicity and austerity of Protestant architecture, art and music, though Lutheran Baroque art developed in parts of Europe as well. The Baroque style used contrast, movement, exuberant detail, deep colour, grandeur and surprise to achieve a sense of awe. The style began at the start of the 17th century in Rome, then spread rapidly to France, northern Italy, Spain and Portugal, then to Austria and southern Germany. By the 1730s, it had evolved into an even more flamboyant style, called rocaille or Rococo, which appeared in France and central Europe until the mid to late 18th century.Bauhaus
The Staatliches Bauhaus (German: [ˈʃtaːtlɪçəs ˈbaʊˌhaʊs] (listen)), commonly known as the Bauhaus, was a German art school operational from 1919 to 1933 that combined crafts and the fine arts, and was famous for the approach to design that it publicized and taught.The Bauhaus was founded by Walter Gropius in Weimar. The German term Bauhaus—literally "building house"—was understood as meaning "School of Building", but in spite of its name and the fact that its founder was an architect, the Bauhaus did not have an architecture department during its first years of existence. Nonetheless, it was founded with the idea of creating a "total" work of art (Gesamtkunstwerk) in which all arts, including architecture, would eventually be brought together. The Bauhaus style later became one of the most influential currents in modern design, Modernist architecture and art, design and architectural education. The Bauhaus had a profound influence upon subsequent developments in art, architecture, graphic design, interior design, industrial design, and typography.The school existed in three German cities: Weimar from 1919 to 1925, Dessau from 1925 to 1932, and Berlin from 1932 to 1933, under three different architect-directors: Walter Gropius from 1919 to 1928, Hannes Meyer from 1928 to 1930, and Ludwig Mies van der Rohe from 1930 until 1933, when the school was closed by its own leadership under pressure from the Nazi regime, having been painted as a centre of communist intellectualism. Although the school was closed, the staff continued to spread its idealistic precepts as they left Germany and emigrated all over the world.The changes of venue and leadership resulted in a constant shifting of focus, technique, instructors, and politics. For example, the pottery shop was discontinued when the school moved from Weimar to Dessau, even though it had been an important revenue source; when Mies van der Rohe took over the school in 1930, he transformed it into a private school, and would not allow any supporters of Hannes Meyer to attend it.Brutalist architecture
Brutalist architecture or Brutalism is an architectural style which emerged in the mid-20th century and gained popularity in the 1970s. It descended from the modernist architectural movement of the early 20th century. It is characterized by simple, block-like structures that often feature bare building materials. Exposed concrete is favored in construction, however some examples are primarily made of brick. Though beginning in Europe, Brutalist architecture can now be found around the world. The style has been most commonly used in the design of institutional buildings such as libraries, courts, public housing and city halls.
Brutalism's stark, geometric designs contrast with the more ornate features of some 1930s and 1940s architecture. Brutalist designs have historically been polarising. Specific buildings, as well as the movement as a whole, have drawn a range of criticism and support from architects and the public. Many brutalist buildings have become architectural and cultural icons, with some obtaining listed status.Burj Khalifa
The Burj Khalifa (Arabic: برج خليفة, Arabic for "Khalifa Tower"; pronounced English: ), known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. With a total height of 829.8 m (2,722 ft) and a roof height (excluding antenna) of 828 m (2,717 ft), the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009.Construction of the Burj Khalifa began in 2004, with the exterior completed five years later in 2009. The primary structure is reinforced concrete. The building was opened in 2010 as part of a new development called Downtown Dubai. It is designed to be the centrepiece of large-scale, mixed-use development. The decision to construct the building is based on the government's decision to diversify from an oil-based economy, and for Dubai to gain international recognition. The building was originally named Burj Dubai but was renamed in honour of the ruler of Abu Dhabi and president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan; Abu Dhabi and the UAE government lent Dubai money to pay its debts. The building broke numerous height records, including its designation as the tallest building in the world.
Burj Khalifa was designed by Adrian Smith, of Skidmore, Owings & Merrill, whose firm designed the Willis Tower and One World Trade Center. Hyder Consulting was chosen to be the supervising engineer with NORR Group Consultants International Limited chosen to supervise the architecture of the project. The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra. The Y-shaped tripartite floor geometry is designed to optimize residential and hotel space. A buttressed central core and wings are used to support the height of the building. Although this design was derived from Tower Palace III, the Burj Khalifa's central core houses all vertical transportation with the exception of egress stairs within each of the wings. The structure also features a cladding system which is designed to withstand Dubai's hot summer temperatures. It contains a total of 57 elevators and 8 escalators.
At a certain point in the architectural and engineering process, the original Emaar developers ran into financial issues, and required more money and economic funding. Sheikh Khalifa, the ruler of the United Arab Emirates, granted monetary aid and funding, hence resulting in the changing of the name to "Burj Khalifa". The concept of profitability derived from building high density developments and malls around the landmark have proven successful. Its surrounding malls, hotels and condominiums in Downtown Dubai have generated the most revenue from the project as a whole, while the Burj Khalifa itself made little or no profit.Critical reception to Burj Khalifa has been generally positive, and the building has received many awards. There were complaints concerning migrant workers from South Asia who were the primary building labor force. These centered on low wages and the practice of confiscating passports until duties were complete. Several suicides were reported.Frank Lloyd Wright
Frank Lloyd Wright (June 8, 1867 – April 9, 1959) was an American architect, interior designer, writer, and educator, who designed more than 1,000 structures, 532 of which were completed. Wright believed in designing structures that were in harmony with humanity and its environment, a philosophy he called organic architecture. This philosophy was best exemplified by Fallingwater (1935), which has been called "the best all-time work of American architecture". His creative period spanned more than 70 years.
Wright was the pioneer of what came to be called the Prairie School movement of architecture, and he also developed the concept of the Usonian home in Broadacre City, his unique vision for urban planning in the United States. In addition to his houses, Wright designed original and innovative offices, churches, schools, skyscrapers, hotels, museums, and other structures. He often designed interior elements for these buildings, as well, including furniture and stained glass. Wright wrote 20 books and many articles and was a popular lecturer in the United States and Europe. Wright was recognized in 1991 by the American Institute of Architects as "the greatest American architect of all time".His colorful personal life often made headlines, notably for leaving his first wife, Catherine Lee "Kitty" Tobin for Mamah Borthwick Cheney, the murders at his Taliesin estate in 1914, his tempestuous marriage with second wife Miriam Noel, and his relationship with Olga (Olgivanna) Lazovich Hinzenburg, who became his third wife in 1928.Gothic Revival architecture
Gothic Revival (also referred to as Victorian Gothic, neo-Gothic, or Gothick) is an architectural movement popular in the Western World that began in the late 1740s in England. Its popularity grew rapidly in the early 19th century, when increasingly serious and learned admirers of neo-Gothic styles sought to revive medieval Gothic architecture, in contrast to the neoclassical styles prevalent at the time. Gothic Revival draws features from the original Gothic style, including decorative patterns, finials, lancet windows, hood moulds and label stops.
The Gothic Revival movement emerged in 18th-century England, gaining ground in the 19th. Its roots were intertwined with deeply philosophical movements associated with Catholicism and a re-awakening of High Church or Anglo-Catholic belief concerned by the growth of religious nonconformism. Ultimately, the "Anglo-Catholicism" tradition of religious belief and style became widespread for its intrinsic appeal in the third quarter of the 19th century. Gothic Revival architecture varied considerably in its faithfulness to both the ornamental style and principles of construction of its medieval original, sometimes amounting to little more than pointed window frames and a few touches of Gothic decoration on a building otherwise on a wholly 19th-century plan and using contemporary materials and construction methods.
In parallel to the ascendancy of neo-Gothic styles in 19th-century England, interest spread rapidly to the continent of Europe, in Australia, Sierra Leone, South Africa and to the Americas; the 19th and early 20th centuries saw the construction of very large numbers of Gothic Revival and Carpenter Gothic structures worldwide. The influence of the Revival had nevertheless peaked by the 1870s. New architectural movements, sometimes related as in the Arts and Crafts movement, and sometimes in outright opposition, such as Modernism, gained ground, and by the 1930s the architecture of the Victorian era was generally condemned or ignored. The later 20th century saw a revival of interest, manifested in the United Kingdom by the establishment of the Victorian Society in 1958.Gothic architecture
Gothic architecture is a style that flourished in Europe during the High and Late Middle Ages. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. Originating in 12th-century France, it was widely used, especially for cathedrals and churches, until the 16th century.
Its most prominent features included the use of the rib vault and the flying buttress, which allowed the weight of the roof to be counterbalanced by buttresses outside the building, giving greater height and more space for windows. Another important feature was the extensive use of stained glass, and the rose window, to bring light and color to the interior. Another feature was the use of realistic statuary on the exterior, particularly over the portals, to illustrate biblical stories for the largely illiterate parishioners. These technologies had all existed in Romanesque architecture, but they were used in more innovative ways and more extensively in Gothic architecture to make buildings taller, lighter and stronger.
The first notable example is generally considered to be the Abbey of Saint-Denis, near Paris, whose choir and facade were reconstructed with Gothic features. The choir was completed in 1144. The style also appeared in some civic architecture in northern Europe, notably in town halls and university buildings. A Gothic revival began in mid-18th-century England, spread through 19th century Europe and continued, largely for ecclesiastical and university structures, into the 20th century.House
A house is a building that functions as a home. They can range from simple dwellings such as rudimentary huts of nomadic tribes and the improvised shacks in shantytowns to complex, fixed structures of wood, brick, concrete or other materials containing plumbing, ventilation, and electrical systems. Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock (like cattle) may share part of the house with humans. The social unit that lives in a house is known as a household.
Most commonly, a household is a family unit of some kind, although households may also be other social groups, such as roommates or, in a rooming house, unconnected individuals. Some houses only have a dwelling space for one family or similar-sized group; larger houses called townhouses or row houses may contain numerous family dwellings in the same structure. A house may be accompanied by outbuildings, such as a garage for vehicles or a shed for gardening equipment and tools. A house may have a backyard or frontyard, which serve as additional areas where inhabitants can relax or eat.Minimalism
In visual arts, music, and other mediums, minimalism is an art movement that began in post–World War II Western art, most strongly with American visual arts in the 1960s and early 1970s. Prominent artists associated with minimalism include Donald Judd, John McCracken, Agnes Martin, Dan Flavin, Robert Morris, Anne Truitt, and Frank Stella. It derives from the reductive aspects of modernism and is often interpreted as a reaction against abstract expressionism and a bridge to postminimal art practices.
Minimalism in music often features repetition and gradual variation, such as the works of La Monte Young, Terry Riley, Steve Reich, Philip Glass, Julius Eastman, and John Adams. The term minimalist often colloquially refers to anything that is spare or stripped to its essentials. It has accordingly been used to describe the plays and novels of Samuel Beckett, the films of Robert Bresson, the stories of Raymond Carver, and the automobile designs of Colin Chapman.Modern architecture
Modern architecture, or modernist architecture was based upon new and innovative technologies of construction, particularly the use of glass, steel and reinforced concrete; the idea that form should follow function; an embrace of minimalism; and a rejection of ornament.
It emerged in the first half of the 20th century and became dominant after World War II until the 1980s, when it was gradually replaced as the
principal style for institutional and corporate buildings by postmodern architecture.Mosque
A mosque (; from Arabic: مَـسْـجِـد, translit. masjid, lit. place of ritual prostration) is a place of worship for Muslims.Any act of worship that follows the Islamic rules of prayer can be said to create a mosque, whether or not it takes place in a special building. Informal and open-air places of worship are called musalla, while mosques used for communal prayer on Fridays are known as jāmiʿ. Mosque buildings typically contain an ornamental niche (mihrab) set into the wall that indicates the direction of Mecca (qiblah), ablution facilities and minarets from which calls to prayer are issued. The pulpit (minbar), from which the Friday sermon (khutba) is delivered, was in earlier times characteristic of the central city mosque, but has since become common in smaller mosques. Mosques typically have segregated spaces for men and women. This basic pattern of organization has assumed different forms depending on the region, period and denomination.Mosques commonly serve as locations for prayer, Ramadan vigils, funeral services, Sufi ceremonies, marriage and business agreements, alms collection and distribution, as well as homeless shelters. Historically, mosques were also important centers of elementary education and advanced training in religious sciences. In modern times, they have preserved their role as places of religious instruction and debate, but higher learning now generally takes place in specialized institutions. Special importance is accorded to the Great Mosque of Mecca (center of the hajj), Prophet's Mosque in Medina (burial place of Muhammad) and the Al-Aqsa Mosque in Jerusalem (believed to be the site of Muhammad's ascent to heaven). In the past, many mosques in the Muslim world were built over burial places of Sufi saints and other venerated figures, which has turned them into popular pilgrimage destinations.The first mosque was built by Muhammad in Medina. With the spread of Islam, mosques multiplied across the Islamic world. Sometimes churches and other temples were converted into mosques, which influenced Islamic architectural styles. While most pre-modern mosques were funded by charitable endowments, modern states in the Muslim world have attempted to bring mosques under government control. Increasing government regulation of large mosques has been countered by a rise of privately funded mosques of various affiliations and ideologies, many of which serve as bases for different Islamic revivalist currents and social activism. Mosques have played a number of political roles. The rates of mosque attendance vary widely depending on the region.Neoclassical architecture
Neoclassical architecture is an architectural style produced by the neoclassical movement that began in the mid-18th century. In its purest form, it is a style principally derived from the architecture of classical antiquity, the Vitruvian principles, and the work of the Italian architect Andrea Palladio.In form, neoclassical architecture emphasizes the wall rather than chiaroscuro and maintains separate identities to each of its parts. The style is manifested both in its details as a reaction against the Rococo style of naturalistic ornament, and in its architectural formulae as an outgrowth of some classicising features of the Late Baroque architectural tradition. Neoclassical architecture is still designed today, but may be labelled New Classical Architecture for contemporary buildings.
In Central and Eastern Europe, the style is usually referred to as Classicism (German: Klassizismus, Russian: Классицизм), while the newer revival styles of the 19th century until today are called neoclassical.Neoclassicism
Neoclassicism (also spelled Neo-classicism; from Greek νέος nèos, "new" and Greek κλασικός klasikόs, "of the highest rank") is the name given to Western movements in the decorative and visual arts, literature, theatre, music, and architecture that draw inspiration from the "classical" art and culture of classical antiquity. Neoclassicism was born largely thanks to the writings of Johann Joachim Winckelmann, at the time of the rediscovery of Pompeii and Herculaneum, but its popularity spread all over Europe as a generation of European art students finished their Grand Tour and returned from Italy to their home countries with newly rediscovered Greco-Roman ideals. The main Neoclassical movement coincided with the 18th-century Age of Enlightenment, and continued into the early 19th century, laterally competing with Romanticism. In architecture, the style continued throughout the 19th, 20th and up to the 21st century.
European Neoclassicism in the visual arts began c. 1760 in opposition to the then-dominant Rococo style. Rococo architecture emphasizes grace, ornamentation and asymmetry; Neoclassical architecture is based on the principles of simplicity and symmetry, which were seen as virtues of the arts of Rome and Ancient Greece, and were more immediately drawn from 16th-century Renaissance Classicism. Each "neo"-classicism selects some models among the range of possible classics that are available to it, and ignores others. The Neoclassical writers and talkers, patrons and collectors, artists and sculptors of 1765–1830 paid homage to an idea of the generation of Phidias, but the sculpture examples they actually embraced were more likely to be Roman copies of Hellenistic sculptures. They ignored both Archaic Greek art and the works of Late Antiquity. The "Rococo" art of ancient Palmyra came as a revelation, through engravings in Wood's The Ruins of Palmyra. Even Greece was all-but-unvisited, a rough backwater of the Ottoman Empire, dangerous to explore, so Neoclassicists' appreciation of Greek architecture was mediated through drawings and engravings, which subtly smoothed and regularized, "corrected" and "restored" the monuments of Greece, not always consciously.Romanesque architecture
Romanesque architecture is an architectural style of medieval Europe characterized by semi-circular arches. There is no consensus for the beginning date of the Romanesque style, with proposals ranging from the 6th to the 11th century, this later date being the most commonly held. In the 12th century it developed into the Gothic style, marked by pointed arches. Examples of Romanesque architecture can be found across the continent, making it the first pan-European architectural style since Imperial Roman architecture. The Romanesque style in England is traditionally referred to as Norman architecture.
Combining features of ancient Roman and Byzantine buildings and other local traditions, Romanesque architecture is known by its massive quality, thick walls, round arches, sturdy pillars, barrel vaults, large towers and decorative arcading. Each building has clearly defined forms, frequently of very regular, symmetrical plan; the overall appearance is one of simplicity when compared with the Gothic buildings that were to follow. The style can be identified right across Europe, despite regional characteristics and different materials.
Many castles were built during this period, but they are greatly outnumbered by churches. The most significant are the great abbey churches, many of which are still standing, more or less complete and frequently in use. The enormous quantity of churches built in the Romanesque period was succeeded by the still busier period of Gothic architecture, which partly or entirely rebuilt most Romanesque churches in prosperous areas like England and Portugal. The largest groups of Romanesque survivors are in areas that were less prosperous in subsequent periods, including parts of southern France, rural Spain and rural Italy. Survivals of unfortified Romanesque secular houses and palaces, and the domestic quarters of monasteries are far rarer, but these used and adapted the features found in church buildings, on a domestic scale.Service-oriented architecture
Service-oriented architecture (SOA) is a style of software design where services are provided to the other components by application components, through a communication protocol over a network. The basic principles of service-oriented architecture are independent of vendors, products and technologies.
A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online.
A service has four properties according to one of many definitions of SOA:
It logically represents a business activity with a specified outcome.
It is self-contained.
It is a black box for its consumers.
It may consist of other underlying services.SOA was first termed Service-Based Architecture in 1998 by a team developing integrated foundational management services and then business process-type services based upon units of work and using CORBA for inter-process communications.
Different services can be used in conjunction to provide the functionality of a large software application, a principle SOA shares with modular programming. Service-oriented architecture integrates distributed, separately-maintained and -deployed software components. It is enabled by technologies and standards that facilitate components' communication and cooperation over a network, especially over an IP network.Taj Mahal
The Taj Mahal (; Hindi: ताज महल [taːdʒ ˈmɛːɦ(ə)l], meaning "Crown of the Palaces") is an ivory-white marble mausoleum on the south bank of the Yamuna river in the Indian city of Agra. It was commissioned in 1632 by the Mughal emperor, Shah Jahan (reigned from 1628 to 1658), to house the tomb of his favourite wife, Mumtaz Mahal. It also houses the tomb of Shah Jahan, the builder. The tomb is the centerpiece of a 17-hectare (42-acre) complex, which includes a mosque and a guest house, and is set in formal gardens bounded on three sides by a crenellated wall.
Construction of the mausoleum was essentially completed in 1643 but work continued on other phases of the project for another 10 years. The Taj Mahal complex is believed to have been completed in its entirety in 1653 at a cost estimated at the time to be around 32 million rupees, which in 2015 would be approximately 52.8 billion rupees (U.S. $827 million). The construction project employed some 20,000 artisans under the guidance of a board of architects led by the court architect to the emperor, Ustad Ahmad Lahauri.
The Taj Mahal was designated as a UNESCO World Heritage Site in 1983 for being "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage". It is regarded by many as the best example of Mughal architecture and a symbol of India's rich history. The Taj Mahal attracts 7–8 million visitors a year and in 2007, it was declared a winner of the New7Wonders of the World (2000–2007) initiative.
