BauderGREEN Sedum System with Bauder Total Green Roof System (BTGRS)


Overlooking the Queen Elizabeth II Bridge and the Thames, the workshop features a vaulted ceiling, which is 19 metres at its highest point to accommodate the full-scale scenery which is built by the 30 full-time craftspeople employed there.

This £8.3m building is used by London’s Royal Opera House to build scenery for its elaborate ballet and operatic performances. Located at the £60m High House Production Park, in Purfleet, which opened at the end of 2010, the workshop boasts outstanding green credentials.
