An architect is a person who is involved in the planning, designing and oversight of a building's construction. The word "architect" (Latin: architectus) derives from the Greek arkhitekton (arkhi (chief) + tekton (builder))") . In the broadest sense an architect is a person who translates the user's needs into a physical, built solutionoun An architect must thoroughly understand the building and operational codes under which his or her design must conform. That degree of knowledge is necessary so that he or she is not apt to omit any necessary requirements, or produce improper, conflicting, ambiguous, or confusing requirements. Architects must understand the various methods available to the builder for building the client's structure, so that he or she can negotiate with the client to produce a best possible compromise of the results desired within explicit cost and time boundaries. The idea of what constitutes a result desired varies among architects, as the values and attitudes which underlie modern architecture differ both between the schools of thought which influence architecture and between individual practising architects.
