Architects practice the art and science of creating, preserving and remodeling buildings. Ideally they work to articulate an image of the client who owns the building, what happens there and what it means to the community. Once the aesthetic and functional aspects of a design are conceived, engineers and other professionals are consulted to make the building work according to the laws of physics, safety and access codes, and necessitates such as electricity and plumbing. Architects are required to have a working knowledge of all these building elements.
