The RIBA is set to acquire the late Sir Leslie Martin's architectural archive, after it was secured by the government. The DCMS has accepted the valuable collection from Martin's family in place of £245,000 in inheritance tax. The culture secretary is now considering a request from Martin's widow that it be put in trust to the RIBA.
The move means that the RIBA could receive the collection without having to use its own funds.
A spokesperson for the DCMS said the RIBA would be a 'prime candidate' to receive the archive, which includes correspondence, teaching documents, architectural drawings, plans and models.
Martin's daughter, Sue Mason, said the contents included work from Martin's architectural practice and documents relating to The Circle publication, which he founded with painter Ben Nicholson and sculptor Naum Gabo.
Martin, who died in 2000, is best known for the Royal Festival Hall and post-war university buildings in Cambridge, Hull and Oxford.
The fate of another substantial collection, that of the late Sir Denys Lasdun, has still to be decided although the RIBA is keen to acquire it.
The RIBA's distinguished collection is set to go on public display next year in a new Gareth Hoskins-designed architecture gallery in London's Victoria and Albert Museum as part of the institute's Architecture for All project.
