'So we saved that money and then the roof itself was less expensive. 'We got to take about two-thirds of the steel out of the house,' said Renfro. A series of staircases allow circulation among the split levels of the living area Renfro told Dezeen that the material was chosen because the original plan, to use concrete, proved to be too expensive and too heavy. This was made by cladding the foam monocoque structure with Glass Fiber Reinforced Polymer (GFRP), fabricated by aerospace design firm Janicki Industries in Seattle. On top of this dune-like procession of spaces is the sculptural roof with a 'compound curvature,' according to Renfro. 'It could be described as split-level, since the entry is at an intermediate level, and all the main living spaces are either up or down a half or full flight of stairs from there.' Floor-to-ceiling glass opens up the primary living space 'Neither a conventional floor plan nor a conventional section drawing is of much help in understanding how the interior of the house works,' Goldberger wrote. The interiors are characterised by a smooth continuous finish between the walls, floors and ceilings

Two bedrooms for children were stepped down, partially below grade. The study is perched above this space, and the primary bedroom occupies a cantilevered top floor that sticks out from the structure on the other side. The design of the home proceeds as a series of platforms, with a primary living space occupying the main level, with an expansive, wrap-around glass window that provides views of the ocean. 'It is really surreal and magical in the whole the whole roof just feels like it's floating.' A study and a primary bedroom were elevated above the main living area It stands out from the dune while taking a lot of its cues from ,' continued Renfro.

'It's not like a bunker built into the earth, it's actually intentionally its own thing. However, the concrete foundation and dramatic roofline make the 10,000-square-foot home stand apart from its environment.
