Melrose, Johannesburg, 490sqm. Designed with Bauhaus principles in mind, this new house is an overhanging, symmetrical box resting on a grid of concrete columns, the windows are long horizontal bands, the flat concrete roof is trafficable (there are plans to green it) and none of the interior walls are load-bearing. The façades accentuate the concrete grid frame by offsetting the raw concrete columns with slick Marmoran-coated infill brickwork in a dark “black-coffee” colour. Likewise, on the interior, the raw off-shutter concrete floors, walls and ceilings contrast with the other smooth, white surfaces.
