working details: Coffered precast concrete slab floor
The first floor of the two-storey office building consists of a series of coffered precast concrete slabs supported on precast columns. Precast was chosen for its energy efficiency - the concrete mass provides thermal energy storage - and to keep the overall height of the building as low as possible. A suspended ceiling is not needed as services are contained in the suspended floor above the slab. The slabs incorporate pipework carrying chilled water for office cooling.
