Lord Palumbo has given Mies van der Rohe's Mansion House Square archive—which includes models, photographs, and films—to the RIBA Collections.

It also includes original feasibility drawings, bronze door handles and hinges, photomontages by architectural photographer John Donat and historical documents and objects related to the hotly-debated development.
