This kitchen extension - clad in black zinc, with standing seams tracing a path across the roof - was defined by the geometry of the main house

Two solid doors lead onto granite terraces - the larger door weighs 300kg. The open-plan space is divided by a long work bench clad in mitred Assaluto Nero granite. A step down into the kitchen allows this bench to form a counter top and cantilevered table. The white ash floorboards and white facets of the ceiling form a bright lining to the dark outer-shell. The planes of the extension shift and tilt, alternating with triangular roof lights that frame views of the trees and chimney-pots beyond.

Cost: £246,000
