Architecture

Architecture is the art and science of designing buildings and structures. A wider definition often includes the design of the total built environment: from the macrolevel of town planning, urban design, and landscape architecture to the microlevel of construction details and furniture. The term "Architecture" is also used for the profession of providing architectural services.

Architectural design involves the manipulation of mass, space, volume, texture, light, shadow, materials, program, and other elements in order to achieve an end which is aesthetic as well as functional. This distinguishes Architecture from the applied science of engineering which usually concentrates on the structural and feasibility aspects of design.

Architectural works are perceived as cultural and political symbols and works of art. Historical civilizations are often known primarily through their architectural achievements. Such buildings as the pyramids of Egypt and the Roman Colosseum are cultural symbols, and are an important link in public consciousness, even when scholars have discovered much about a past civilization through other means. Cities, regions and cultures continue to identify themselves with and are known by their architectural monuments. Alberti gives the earliest definition of the role of the architect. The architect is to be concerned firstly with the construction. This encompasses all the practical matters of site, of materials and their limitations and of human capabiliity. The second concern is "articulation"; the building must work and must please and suit the needs of those who use it. The third concern of the architect is aesthetics, both of proportion and of ornament.

The role of the architect is constantly evolving, and is central to the design and implementation of the environments in which people live. In order to obtain the skills and knowledge required to design, plan and oversee a diverse range of projects, architects must go through extensive formal education, coupled with a requisite amount of professional practice.

The work of an architect is an interdisciplinary field, drawing upon mathematics, science, art, technology, social sciences, politics and history, and often governed by the architect's personal approach or philosophy. Vitruvius, the earliest known architectural theorist, states: "Architecture is a science, arising out of many other sciences, and adorned with much and varied learning: by the help of which a judgement is formed of those works which are the result of other arts." He adds that an architect should be well versed in other fields of learning such as music and astronomy."Vitruvius"

Theory of Architecture

Historic treatises

The earliest written work on the subject of architecture is De architectura, by the Roman architect Vitruvius in the early 1st century CE. Among the philosophies that have influenced modern architects and their approach to building design are rationalism, empiricism, structuralism, poststructuralism, and phenomenology.

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. To satisfy the modern 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.

There is also a concept among architects that although architecture does not exist in a vacuum, architectural form cannot be merely a compilation of historical precedent, functional necessities, and socially aware concerns, but that to achieve significance, a work of architecture must be a transcendent synthesis of all of the former and a creation of worth in and of itself.

History

This section is a brief history of architectural practice. For a description of architectural styles see main article: History of architecture.

Origins and the ancient world

Architecture 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, architecture became a craft. Here there is first a process of trial and error, and later improvisation or replication of a successful trial. 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 Huyuk in Anatolia and Mohenjo Daro in India. In many ancient civilizations, such as that of the Egyptians' and Mesopotamians', architecture and urbanism reflected the constant engagement with the divine and the supernatural, while in other ancient cultures such as Persia architecture and urban planning was used to exemplify the power of the state.

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 styles developed.

Texts on architecture began to be written in the Classical period. These became canons to be followed in important works, especially religious architecture. Some examples of canons are found in the writings of Vitruvius, the KaoGongJi of ancient China and Vaastu Shastra of ancient India.

The architecture of different parts of Asia developed along different lines to that of Europe, Buddhist, Hindu and Sikh architecture each having different characteristics. Buddhist architecture, in particular, showed great regional diversity. In many Asian countries a pantheistic religion led to architectural forms that were designed specifically to enhance the natural landscape.

The Medieval builder

Islamic architecture began in the 7th century CE, developing from the architectural forms of the ancient Middle East but developing features to suit the religious and social needs of the society. Examples can be found throughout the Middle East, North Africa and Spain, and were to become a significant stylistic influence on European architecture during the Medieval period.

In Europe, in both the Classical and Medieval periods, buildings were not attributed to specific individuals and the names of the architects frequently unknown, despite the vast scale of the many religious buildings extant from this period. During the Medieval period guilds were formed by craftsmen to organise their trade and written contracts have survived, particularly in relation to ecclesiastical buildings. The role of architect was usually one with master builder, except in the case where a cleric, such as the Abbot Suger at Saint Denis, Paris, provided the design. Over time the complexity of buildings and their types increased. General civil construction such as roads and bridges began to be built. Many new building types such as schools, hospitals, and recreational facilities emerged.

Renaissance and the architect

With the Renaissance and its emphasis on the individual and humanity rather than religion, and with all its attendant progress and achievements, a new chapter began. Buildings were ascribed to specific architects - Brunelleschi, Alberti, Michelangelo, Palladio - and the cult of the individual had begun. But there was no dividing line between artist, architect and engineer, or any of the related vocations. 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.

The Industrial Revolution

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 lose ground on some technical aspects of building design. He therefore concentrated on aesthetics and the humanist aspects. 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, at, for example Ecole des Beaux Arts in France, gave much emphasis to the production of beautiful drawings and little to context and feasibility. Effective architects generally received their training in the offices of other architects, graduating to the role from draughtsmen or clerks.

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.

Modernism and reaction

The dissatisfaction with such a general situation at the turn of the twentieth century 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 Germany in 1919, consciously rejected history and looked at architecture as a synthesis 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 that displayed their construction and structure, exposing steel beams and concrete surfaces instead of hiding them behind traditional forms, were seen as beautiful in their own right. Architects such as Mies van der Rohe 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.

Many architects resisted Modernism, finding it devoid of the decorative richness of ornamented styles. As the founders of the International Style lost influence in the late 1970s, Postmodernism developed as a reaction against the austerity of Modernism. Robert Venturi's contention that a "decorated shed" (an ordinary building which is functionally designed inside and embellished on the outside) was better than a "duck" (a building in which the whole form and its function are tied together) gives an idea of this approach.

Architecture today

Part of the architectural profession, and also some non-architects, responded to Modernism and Postmodernism by going to what they considered the root of the problem. They felt that architecture was not a personal philosophical or aesthetic pursuit by individualists; rather it had to consider everyday needs of people and use technology to give a livable environment. The Design Methodology Movement involving people such as Christopher Alexander started searching for more people-oriented designs. Extensive studies on areas such as behavioral, environmental, and social sciences were done and started informing the design process.

As many other concerns began to be recognized and the complexity of buildings began to increase (in terms of aspects such as structural systems, services and technologies), architecture started becoming more multi-disciplinary than ever. Architecture today usually requires a team of specialist professionals, with the architect being one of many, although usually the team leader.

During the last two decades of the twentieth century and into the new millennium, the field of architecture saw the rise of specializations within the profession itself by project type, technological expertise or project delivery methods. In addition, there has been an increased separation of the 'design' architect from the 'project' architect within some architectural office collaborations.

One of most significant recent developments in the profession is the mainstreaming of sustainability. Sustainability in architecture was pioneered in the 1970s by architects such as Edward Mazria and Ian McHarg in the US and Brenda and Robert Vale in the UK and New Zealand. The acceleration in numbers of buildings which seek to meet sustainable design principles is inline with a growing world-wide awareness of the risks of climate change. It is now widely expected of an architect that they will integrate sustainable principals into their projects. The U.S. Green Building Council's LEED (Leadership in Energy and Environmental Design) rating system has been instrumental in this. Other green building rating systems include Energy Star, Green Globes, and CHPS (Collaborative for High Performance Schools).
