Villa Casa in Mt Washington, California by Los Angeles-based Space International, is charming and peaceful home with a Hollywood-style illusion. This grassy lawn looks as if it is a flat, ground level lawn.
But actually the house is located on a steep hillside. This patio is
grassed in to seem like ground level. Terraces make it seem as if it is
on flat ground.
And, in fact, this swimming pool is actually forming a retaining wall at the bottom of the steeply sloping original lot.
The structural Engineers, David H. Lau and David Maynard make the
pool do double duty as a bulwark against the steep site so that a flat
lawn can be made behind it.
