Architectural work is typically divided into a sequence of different ‘Stages’ which can be commissioned as a whole or separately. The RIBA’s ‘Plan of Work 2013’ sets out the key stages of a construction project from conception to completion using eight stages (0 to 7).

​

While the stages generally occur sequentially, on some projects aspects of the design might be developed earlier than others, or project constraints may make it necessary to overlap certain stages.
