These roof planes became the driving force behind the design, penetrating the interiors to form bulkheads. They also tie the house to the view, with the prominent line of the horizon in the distance.
The strong horizontal planes in white contrast with the vertical support elements clad in dark basalt stone. These form a central spine through the house, starting at the front exterior, penetrating into the entrance way, through the living spaces and out to a west-facing outdoor entertaining and cooking area.
In the living area, this vertical element houses a central fireplace and divides the seating and dining areas. As seen elsewhere in the house, associated cabinetry is designed to give the sense of floating.
"I tried not to have cabinetwork touch the floor," says Banham. "I wanted to have it cantilever as much as I could, like the balconies and roof line."
The west outdoor area is covered by a six-metre cantilevered roof, including operable louvres. However, this alone doesn't provide enough protection from the prevailing winds.
For that, the architect created an even more sheltered area on the north face of the building. Referred to as the atrium, this inset terrace is glazed on three sides.
Bifolding doors can be opened up all round to give a completely protected indoor-outdoor space, Banham says.
