"At the same time we dropped the garage level by two metres, which reduced the steepness of the driveway, so as to allow easier access for the owners' sports cars," says Rhoda.
"The garage doors are made of dark aluminium and this same material is used to clad the whole wall at this level, so the doors effectively disappear from sight."
The steepness of the site also allowed the architects to split the house into three floors the basement garage level, the living areas and the bedroom wing, which forms the top floor on the long arm of the L.
The entrance cube and bedroom level are constructed of raw shuttered concrete, which is softened by the use of a natural stone cladding for the wall between them that shields the living areas.
A white, geometrically shaped screen installed on the upper level adds patterned textures to the exterior. Like much of the design of the house, this screen was inspired by Japanese architecture and culture incorporating transparency and using materials in unusual ways.
"Although this is a screening device for the bedrooms, it still allows natural light in and access to the views. And while it's made of heavy, solid steel, it looks quite flimsy, like origami," says Rhoda.
