An architect is a person who plans, designs and oversees 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, the term architect derives from the Latin ''architectus'', which derives from the Greek (''arkhi-'', chief + ''tekton'', builder), i.e., chief builder. The

Origins

Throughout ancient and medieval history, most of the architectural design and construction was carried out by

. In Europe, the titles ''architect'' and ''engineer'' were primarily geographical variations that referred to the same person, often used interchangeably. "Architect" derives from Greek (, "master builder", "chief ). It is suggested that various developments in technology and mathematics allowed the development of the professional 'gentleman' architect, separate from the hands-on craftsman. Paper was not used in Europe for drawing until the 15th century but became increasingly available after 1500. Pencils were used more often for drawing by 1600. The availability of both allowed pre-construction drawings to be made by professionals. Concurrently, the introduction of linear perspective and innovations such as the use of different projections to describe a three-dimensional building in two dimensions, together with an increased understanding of dimensional accuracy, helped building designers communicate their ideas. However, the development was gradual. Until the 18th-century, buildings continued to be designed and set out by craftsmen with the exception of high-status projects.


Architecture

In most developed countries, only those qualified with an appropriate license, certification, or registration with a relevant body (often governmental) may legally practice architecture. Such licensure usually requires a university degree, successful completion of exams, as well as a training period. Representation of oneself as an architect through the use of terms and titles is restricted to licensed individuals by law, although in general, derivatives such as

Practice

In the architectural profession, technical and environmental knowledge, design and construction management, and an understanding of business are as important as design. However, the design is the driving force throughout the project and beyond. An architect accepts a commission from a client. The commission might involve preparing feasibility reports, building audits, the design of a building or of several buildings, structures, and the spaces among them. The architect participates in developing the requirements the client wants in the building. Throughout the project (planning to occupancy), the architect coordinates a design team.

s and other specialists are hired by the client or the architect, who must ensure that the work is coordinated to construct the design.


Design role

The architect, once hired by a client, is responsible for creating a design concept that both meets the requirements of that client and provides a facility suitable to the required use. The architect must meet with, and question, the client in order to ascertain all the requirements (and nuances) of the planned project. Often the full brief is not entirely clear at the beginning: entailing a degree of risk in the design undertaking. The architect may make early proposals to the client, which may rework the very terms of the brief. The "program" (or brief) is essential to producing a project that meets all the needs of the owner. This then is a guide for the architect in creating the design concept. Design proposal(s) are generally expected to be both imaginative and pragmatic. Depending on the place, time, finance, culture, and available crafts and technology in which the design takes place, the precise extent and nature of these expectations will vary. Foresight is a prerequisite as designing buildings is a very complex and demanding undertaking. Any design concept must at a very early stage in its generation take into account a great number of issues and variables which include qualities of space(s), the end-use and life-cycle of these proposed spaces, connections, relations, and aspects between spaces including how they are put together as well as the impact of proposals on the immediate and wider locality. Selection of appropriate materials and technology must be considered, tested and reviewed at an early stage in the design to ensure there are no setbacks (such as higher-than-expected costs) which may occur later. The site and its environs, as well as the culture and history of the place, will also influence the design. The design must also countenance increasing concerns with environmental sustainability. The architect may introduce (intentionally or not), to greater or lesser degrees, aspects of

. A key part of the design is that the architect often consults with engineers, surveyors and other specialists throughout the design, ensuring that aspects such as the structural supports and air conditioning elements are coordinated in the scheme as a whole. The control and planning of construction costs are also a part of these consultations. Coordination of the different aspects involves a high degree of specialized communication, including advanced computer technology such as BIM (

Means of design

Previously, architects employed drawings to illustrate and generate design proposals. While conceptual sketches are still widely used by architects, computer technology has now become the industry standard. However, design may include the use of photos, collages, prints, linocuts,

Environmental role

As current buildings are now known to be high emitters of carbon into the atmosphere, increasing controls are being placed on buildings and associated technology to reduce emissions, increase energy efficiency, and make use of renewable energy sources. Renewable energy sources may be developed within the proposed building or via local or national renewable energy providers. As a result, the architect is required to remain abreast of current regulations that are continually tightening. Some new developments exhibit extremely low energy use or

. However, the architect is also increasingly required to provide initiatives in a wider environmental sense, such as making provision for low-energy transport, natural daylighting instead of artificial lighting, natural ventilation instead of air conditioning, pollution, and waste management, use of recycled materials and employment of materials which can be easily recycled in the future.


Construction role

As the design becomes more advanced and detailed, specifications and detail designs are made of all the elements and components of the building. Techniques in the production of a building are continually advancing which places a demand on the architect to ensure that he or she remains up to date with these advances. Depending on the client's needs and the jurisdiction's requirements, the spectrum of the architect's services during construction stages may be extensive (detailed document preparation and construction review) or less involved (such as allowing a contractor to exercise considerable design-build functions). Architects typically put projects to tender on behalf of their clients, advise on the award of the project to a

, facilitate and then administer a contract of agreement which is often between the client and the contractor. This contract is legally binding and covers a very wide range of aspects including the insurances and commitments of all stakeholders, the status of the design documents, provisions for the architect's access, and procedures for the control of the works as they proceed. Depending on the type of contract utilized, provisions for further sub-contract tenders may be required. The architect may require that some elements are covered by a warranty which specifies the expected life and other aspects of the material, product or work. In most jurisdictions, prior notification to the relevant local authority must be given before commencement on site, thus giving the local authority notice to carry out independent inspections. The architect will then review and inspect the progress of the work in coordination with the local authority. The architect will typically review contractor

is sometimes hired to assist in the design and to manage construction. In many jurisdictions, mandatory certification or assurance of the completed work or part of works is required. This demand for certification entails a high degree of risk - therefore, regular inspections of the work as it progresses on site is required to ensure that is in compliance with the design itself as well as with all relevant statutes and permissions.


Alternate practice and specializations

Recent decades have seen the rise of specializations within the profession. Many architects and architectural firms focus on certain project types (for example, healthcare, retail, public housing, event management), technological expertise or project delivery methods. Some architects specialize as building code,

Professional requirements

Although there are variations from place to place, most of the world's architects are required to register with the appropriate jurisdiction. To do so, architects are typically required to meet three common requirements: education, experience, and examination. Educational requirements generally consist of a
university degree An academic degree is a qualification awarded to students upon successful completion of a course of study in higher education, usually at a college or university. These institutions commonly offer degrees at various levels, usually including unde ...
in architecture. The experience requirement for degree candidates is usually satisfied by a practicum or internship (usually two to three years, depending on jurisdiction). Finally, a Registration Examination or a series of exams is required prior to licensure. Professionals engaged in the design and supervision of construction projects prior to the late 19th century were not necessarily trained in a separate architecture program in an academic setting. Instead, they often trained under established architects. Prior to modern times, there was no distinction between architects and

). The formal study of architecture in academic institutions played a pivotal role in the development of the profession as a whole, serving as a focal point for advances in architectural technology and theory. The use of "Architect" or abbreviations such as "Ar." as a title attached to a person's name is regulated by law in some countries.


Fees

Architects' fee structures are typically based on a percentage of construction value, as a rate per unit area of the proposed construction, hourly rates or a fixed lump sum fee. Combinations of these structures are also common. Fixed fees are usually based on a project's allocated construction cost and can range between 4 and 12% of new construction cost, for commercial and institutional projects, depending on a project's size and complexity. Residential projects range from 12 to 20%. Renovation projects typically command higher percentages, as high as 15-20%. Overall billings for
