Architecture is the art and science of designing buildings and structures. A broader translation of this word encompasses the design of a fully constructed environment: from the macrolevel of hill planning, urban design, and environmental architecture to the microlevel of manufacturing details and, notably, of furniture. The word architecture is still used to refer to the job of providing architectural services.
