Norwood, Johannesburg, 3x 340sqm. A complex of three identical 2-storey houses built almost entirely of cast concrete. The walls, floors and ceilings all have a smooth, exposed concrete finish. The strict rectangular form is “eroded” at the northern corner to create a veranda with an uninterrupted 12m cantilever roof overhang; these spans are possible because the house is made of reinforced concrete. The window and door openings are all much larger than an average house.
