An introspective assemblage of interconnected cubic white spaces, with wide blackbutt floor boards, bubinga veneered joinery and quartzite tiling form this spacious extension to an inner city terrace house. A 5 metre high translucent glazed cuboid, accommodating a lineal array of kitchen, laundry and powder room, plugs onto one side of the house serving the adjacent spaces. A first floor bedroom, reached by bridge, cantilevers over folding doors connecting the living spaces to the paved rear courtyard.
