RAC Bradley Stoke

This RAC building is hard to miss - sitting at the junction of the M4 and M5 motorways, just outside Bristol. In plan, it is triangular, or perhaps more accurately 'cam-shaped', having convex façades and rounded corners. All three elevations are identical. Three floors high, it sits on a base storey which houses some of the more cellular elements of the programme. Above this are two floors of open plan offices. At the centre of the building is a triangular, top-lit atrium, criss-crossed by stairs. Service cores are efficiently placed at each corner. The walls to the two upper floors are totally glazed and lean outwards, with two intermediate rings of brise-soleil. Perhaps the most striking feature is the central mast and viewing gallery. Access to this is via a glazed lift which runs inbetween the two columns. A secondary access is by a minimally detailed transparent stair tower.
