The site sits on a slope, with the rear yard at the elevation of the upper floor, and the architectural response is what gives the project its name. A steel bridge spans from an elevated pool deck at the rear directly into the home's upper storey, giving the bedrooms their own ground plane and a private connection to the garden.

Elsewhere, board-formed concrete walls run the length of the home, tied together with fibreglass formwork ties that disappear once the formwork comes off. Nearly one hundred pieces of structural steel sit inside the structure of this home, with many of them detailed to be seen rather than hidden.
