Burntwood School in Wandsworth, completed in 2014 recently won the Stirling prize at the Royal Institute of British Architects awards. The €50m School re-build project used striking precast elements on the facade and employed Twin Wall and Stair Flights supplied by Oran Pre-Cast for the project. The quality of Twin Wall finish was critical as the walls were to be left exposed in their final state. This quality is evident from the photo across.
