Savill Building, Windsor Great Park that located in United Kingdom, was designed by Glenn Howells Architects. The main feature of the building is its larch gridshell roof, which is clad with green oak. Both the larch and the oak are from The Crown Estate’s own sustainable sources from within the Windsor Estate. It was designed in conjunction with Buro Happold and Robert Haskins Waters Engineers along with The Green Oak Carpentry Company and Inwood Developments from Lewes, Sussex. (Buro Happold and The Green Oak Carpentry Company were also part of the Weald and Downland gridshell team).
The gridshell roof, as a form of engineering a roof structure, allows large spans using (predominantly sustainable) timber. The Savill Building has a low curve – apparently the lowest a gridshell can go – so as not to interrupt the tree line and to benefit from solar gain. Its form in plan (90m long and up to 25m wide) seems to float over the ground like an elm leaf and rises to an elegant tip at each end.
