Tessellated Roof
The British Museum's Great Court.
Designed by Foster and Partners, engineered by Buro Happold and built by Waagner-Biro.
The first step in the recreation of the Great Court was the demolition of the undistinguished post-war buildings that served as bookstacks around the drum of the Reading Room. The southern portico, which was demolished to enlarge the Museum’s entrance hall in the 1870s, has been reinstated to a new design.
To allow the Great Court to be used no matter what the weather, it is covered with an undulating glazed roof. It has no visible supports to detract from the restoration of the classical facades around it. Instead it spans the gap between the facades and the drum of the Reading Room as a self-supporting structure.
The undulating, minimal steel latticework supports 3,312 unique triangular glass panels. Each one is different in size and shape because of the roof’s complex geometric form, which results from the fact that the Reading Room is not exactly in the centre of the Great Court, but is 5 metres closer to the northern portico. A specially written computer programme was required to work out the exact dimensions and angles of each panel, each of which has been sponsored by an individual or company.
