Spadena House or Witch's House in Beverly Hills, California.
The new owners are remodeling it and making it a bit more Gaudian, and I don't like the changes. The yellow is the old one, the... er... "nude" is the new one.
But it looks like a cob house.
I love the wacky window shutters though, and there is a lot of interesting ideas to adjust to my little hobbit hole :-)
BTW, check out this "ideal home" :-)
