Architecture is the art and sience of designing buildings and structures. The word architecture comes from the Greek arkhitekton, "master builder, director of works," from αρχι- (arkhi) "chief" + τεκτων (tekton) "builder, carpenter".
A wider definition would include the design of the built environment, from the macrolevel of town planning, urban design and landscape architecture to the microlevel of creating furniture. Architectural design usually must address both feasibility and cost for the builder, as well as function and aesthetics for the user.
Planned architecture manipulates space, volume, texture, light, shadow, or abstract elements in order to achieve pleasing aesthetics. This distinguishes it from applied science or engineering, which usually concentrate more on the functional and feasibility aspects of the design of constructions or structures.
In the field of building architecture, the skills demanded of an architect range from the more complex, such as for a hospital or a stadium, to the apparently simpler, such as planning residential houses. Many architectural works may be seen also as cultural and political symbols, and/or works of art. The role of the architect, though changing, has been central to the successful (and sometimes less than successful) design and implementation of pleasingly built environments in which people live.
