The house has a single skillion roof-form sloping from the East to the West in the long direction of the site. The roof-form allows the two storey volumes to be at the front, enjoying beautiful harbour views, and the single storey at the rear to mitigate over-shadowing impact on the southern neighbour's out-door living space. This roof form works dramatically in opposition to the site topography, which falls down from West to East. The first floor is clad in weatherboards and painted white, giving the sense of a large triangular form hovering over the more visually-recessive ground floor.
