C-section steel columns. However the roof structure is different. Plywood box beams span the width of the activity space, secured onto steel beams (which are in turn supported by columns) spanning the length. A sprung floor is built on top of the concrete slab, meanwhile screed is poured onto the decking to create a solid and even first floor surface. Once a damp proof membrane is wrapped around the building, it is insulated and clad. This is followed by the introduction of windows and roof tiles supported by a tertiary structure of battens and counter battens.
Ventilation Warm air rises upwards in the two-storey activity space and escapes through the glazing of the roof lights directly above as well as the north-east facing windows.
Winter sun vs. Summer Sun Due to the cave-like nature of the activity space, users are sheltered from the glare of direct sunlight for most of the day and the excessive heat that this can cause.
Load path diagram The load from the roof travels down the primary structure and through the concrete raft foundation where it is dispersed into the compacted earth below. The load from the steel roof beams is transferred along the timber box beams, which span the shorter distance of the activity space.
