From the beginning of the project, the Foster team was adamant that the existing buildings should be restored along the principles of the original design. The interior layouts were rearranged and rationalised to reflect the contemporary faculty structures and contemporary teaching practices. Wherever possible, the original fixtures were refurbished and all the carpets replaced with duplicates made by the original supplier. In particular, the team were sensitive in their approach to restoring the facade panel system, which was designed by the French engineer, Jean Prouvé, following Le Corbusier’s ‘Modulor’ proportional system and the principles of flexibility and prefabrication.
