Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes from Latin architectura; from Ancient Greek ἀρχιτέκτων (arkhitéktōn) 'architect'; from ἀρχι- (arkhi-) 'chief', and τέκτων (téktōn) 'creator'. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilisations are often identified with their surviving architectural achievements.

A design is the concept of or proposal for an object, process, or system. Design refers to something that is or has been intentionally created by a thinking agent, though it is sometimes used to refer to the nature of something – its design. The verb to design expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan may also be considered to be a design. A design is expected to have a purpose within a certain context, usually having to satisfy certain goals and constraints, and to take into account aesthetic, functional, economic, environmental or socio-political considerations. Typical examples of designs include architectural and engineering drawings, circuit diagrams, sewing patterns, and less tangible artefacts such as business process models.
