The International Union of Architects is the only international non-governmental organization that represents the world's architects, now estimated to number some 3.2 million in all.

An architect is a person who plans, designs, and oversees the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose. Etymologically, the term architect derives from the Latinarchitectus, which derives from the Greek, i.e., chief builder.
