Main entrance<br />

The planning authority was in agreement that the two<br />

adjoining buildings should be designed to an overall<br />

masterplan. The gateway site was required to<br />

incorporate a landscape corridor and to take into<br />

account the context of existing domestic two and<br />

three storey buildings to the south and east, as well as<br />

the visual impact from distant views.<br />

The building form and construction materials were<br />

driven by a strong environmental emphasis to ensure<br />

the maximum passive environmental control was<br />

achieved. The steel frame solution supports flat<br />

precast concrete floor units that are exposed above<br />

suspended lighting/acoustic rafts. The north and<br />

south wing plan depths are such that natural<br />

ventilation can occur and be driven up through the<br />

central full height atrium space, with air exiting via<br />

BMS controlled louvres at high level. The bold and<br />

simple form has been articulated by the use of<br />

extensive brise soleil, combined with zinc and<br />

terracotta cladding.<br />

The building was required to achieve a BREEAM<br />

“Excellent” rating and this was achieved by a mixture<br />

of passive and active measures:<br />

• Orientation and Shading: The building’s longer<br />

facades are facing broadly south for ease of<br />

solarshading, with vertical brise soleil used where<br />

appropriate to east and west facing facades.<br />

• Depth of Plan and Ventilation: North and south<br />

wings, 15m and 13.5m deep either side of a
