The Queen's College has announced the six teams invited to submit proposals to update the Grade II listed Florey building and Nicholas Hare Architects are on the shortlist.
Completed in 1971 by James Stirling, the new competition brief calls for the provision of modern facilities and exemplary energy design.
The Florey, now forty years old, is regarded as one of the great post-war modernist buildings in Britain. It is among the few surviving works of the architect James Stirling, acclaimed as the most brilliant designer of his generation.
Competition organiser, Malcolm Reading said:
"We are delighted by the quality of response to our call for expressions of interest. These teams are highly seasoned, astute practices who are in their prime. This is an extremely complex project which will require a deal of patience and skill but the renewal of the Florey will be a tremendous asset to Queen's, and indeed Oxford."
