Specification
The academic wings and learning resource centre are supported on exposed reinforced concrete frames and floor slabs. Their steel-framed roofs are covered in insulating standing-seam aluminium. The external walls are faced in insulated render on the ground floor, with aluminium-framed double-glazed curtain walling above. In the academic wings, insulated timber rainscreeen cladding is incorporated into the curtain walling.
The auditorium is supported on reinforced concrete walls lined with birch-faced plywood. External walls are faced in stainless-steel shingles secretly fixed to plywood panelling.
