Weald and Downland Gridshell
The Weald and Downland Gridshell (2002) is a building designed by Buro Happold and Edward Cullinan Architects for the Weald and Downland Open Air Museum: it was a runner-up for the Stirling Prize in 2002. The building is a structural wooden gridshell, constructed of oak sourced from Normandy. Before constructing the Gridshell, members of Buro Happold and the Cullinan practice-built a prototype during their own time on weekends. This was also a self-supporting gridshell, and was used as a temporary entrance canopy on the Pompidou Centre.
