Structural glazed walls bring daylight into three stories of rehearsal space and classrooms in the extension, and the protruding dance studio is suspended beneath its soffit. East-west running trusses were installed between the third and sixth levels to carry the load for the four floors of the expansion, the longest of which has a back span with a cantilever. Some of the trusses’ diagonals needed to be offset to accommodate doors, passageways, and other obstructions. Steel diagonal brace frames extend from the ground to the roof to support the lateral load.
