Housebuilder Barratt continues its series of sculptural buildings with the £23m Centrium development next to Woking station, Surrey. To fit into a narrow, irregular site, Acanthus LW Architects has arranged the 288 dwellings as an undulating block. The scheme also contains shops and restaurants at ground level and 72 affordable dwellings. Handovers by contractor Ardmore Construction will be phased from September to next June. Dunwoody Appleton is services engineer and URS is structural engineer.
