Architects

The architect hired by a client is responsible for creating a design concept that meets the requirements of that client and provides a facility suitable to the required use. In that, the architect must meet with and question the client 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 terms of the brief. The program or brief is essential to producing a project that meets all the needs of the owner — it is a guide for the architect in creating the design concept.
It is generally expected that the design proposal(s)is both imaginative as well as pragmatic, but the precise extent and nature of these expectations will vary, depending on the place, time, finance, culture, and available crafts and technology in which the design takes place.

An architect is a person who plans, designs, and reviews.

Derives from the Latin architectus, which derives from the Greek (arkhi-, chief + tekton, builder), i.e., chief builder.

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.
