A stone ricochets off the water’s surface, the impact causes a momentary displacement of water and surface tension propels it along in a series of seemingly impossible steps. This is the moment - the pleasure and efficient simplicity of that first successful leap - that informs the design of the Skip Stone house. The carved ground plane appears displaced by the inertia of the home alighting upon it and accommodates offstreet parking. An adjacent stair slices into the ground and light from the level above welcomes residents to ascend from the car park. The shell of the home is conceived as a gently folded plane with the outward presence of a river rock: just the right combination of flat and smooth, and worn round in all the right places. The tesselated skin, comprised of BIPV panels, ceramic tile and green roof modular elements nods to the possibility of such a stone’s more crystalline past. The secondary enclosure system is comprised of a folding ribbon wall of glass. A service core longitudinally bisects the home’s interior into public and private spaces and is the distribution and circulation point for HVAC, plumbing and hydronic radiant floors, and electricity. Storage, bathing and cooking functions also quietly reside in the core and the bed and counter space carve out territories in its center.
