This architectural model dates from 1962. John Madin was the architect for BBC Pebble Mill, and his practice was based on the Hagley Road. Notice that behind the office block is the helix car park and outside broadcast garage, which was never built. Apparently Birmingham City Council had insisted on ample car parking provision in giving the building planning permission. I understand that it wasn’t built due to costs, at a time when the BBC was being hard hit by ITV, and when the Licence Fee wasn’t increasing much.
