The recession could put an end to new high-quality school buildings, the outgoing head of the Commission for Architecture and the Built Environment has said. Sir John Sorrell, speaking at the Partnerships for Schools design conference, said progress which had seen better-designed classrooms was under threat and called for continued investment. "We must keep on investing in the school estate. And don't imagine that refurbishment and makeovers will solve all the problems. We still need to be investing in new-build schools," he said.
