Conceived as a kind of life-size Jenga tower, this 3-storey stack of cantilevering, perpedicular modules is arranged on a steeply sloping sandy site on the Sunshine Coast.
The site has expansive views over natural landscape to the ocean to the south and east, so all of the walls facing this direction are glass.
Designed to adapt to changing conditions, the house can operate as a well-appointed 4 bedroom + 4 bathroom family home, with the option for 2 self-contained suites on the middle level for visiting adult kids and provision for a future renovation on the lower level.
The house is designed to take full advantage of its hinterland position overlooking the ocean. The upper level features a 13m long wall of floor-to-ceiling glazing which opens the master bedroom, living, kitchen and dining rooms to unobstructed ocean views. These rooms open out onto 2 rooftop gardens which sit 7m above the sand below.
The two roof gardens are joined by a timber bridge which meets an indoor/ outdoor breakfast bar and the kitchen can open completely to the roof gardens via a sill-less vertical bi-folding window from bench height to ceiling.
On the northern side, the site drops away from the road edge and the building hovers above the slope below. Entry is via a slender galvanised steel bridge which incorporates folded steel stairs and grated vehicle ramp.
Another folded steel stair leads to the middle level. A large open deck faces the ocean with separate living volumes on each side, each with floor-to-ceiling, full-width sliding doors onto private balconies.
The house has a number of high-performance specifications including closed-cell spray foam roof insulation, floors and walls between living areas utilise acoustic batts and wall lining, and all floors are thermally insulated. Rainwater is collection and distributed with the latest silent, submersible pump technology.
The modules achieve a 5.5m cantilever, also designed to support a spa bath on the end of the roof deck above.
