An architect is a person who plans, designs, and reviews the construction of buildings. To practice, architecture means to provide services in connection with the design of buildings and space. Also, within site surrounding the buildings, which have as their principal purpose human occupancy or use. Etymologically, they derive from the Latin architecture, which derives from the Greek (arkhi-, chief + tekton, builder), i.e., chief builder. Professionally, an architect’s decisions affect public safety, and thus, one must undergo specialised training consisting of advanced education and a practicum (or internship) for practical experience to earn a license to practice architecture.

The terms architect and architecture also commonly used in the disciplines of landscape architecture, and naval architecture. The titles protected by statute in the United Kingdom and should only use by Architects registered in the UK with the Architects Registration Board (ARB).
