Definition: In the world of architectural design and urban planning, a charrette is an intense period of design or planning activity that can last for one or more days. The term may refer to any collaborative session in which a group of designers drafts a solution to a design problem. Charrettes sometimes involve many stakeholders in a development project, such as municipal representatives, mechanical, civil and electrical engineers, contractors, architects, developers, building owners and sometimes local residents. Such charrettes serve to quickly generate a design solution while integrating the expertise and interests of the diverse group of stakeholders.
