A CLERESTORY AND GLAZED WALL WITH SLIDING OAK SHUTTERS
The building follows the single-storey monopitch shape of the original farm building.
East, west and north walls are of cavity brickwork. In contrast, the south wall is an assembly of storey-height glazed panels and timber-boarded panels, with a glazed clerestory running just below the roof.
Storey-height oak shutters slide across the glazed panels to the meeting room, office and main entrance to give security, solar control, and, in the case of the meeting room, black-out conditions.
The meeting room projects 1.4m beyond the line of the wall for large assemblies.
The roof consists of 1,200mm-wide and 150mm-deep hollow-core concrete planks topped with rigid insulation and profiled fibre-cement panels. The concrete planks create a column-free span in the meeting room; the soffits are exposed to allow the thermal mass to moderate internal temperature. The planks were grouted together at the joints and reinforced at the lower edge in order to act as a structural diaphragm.
Above the clerestory, the planks are slotted and grouted into a 200 x 90mm PFC which has a series of 10mm diameter bars welded into it. The PFC is the inner of a pair of PFCs which are set back-to-back, insulated and supported on 80 x 80mm SHS posts.
