These two caught my eye because they were one after the other on Tréndir and they couldn't be more different. I am partial to areas enclosed by walls but open to the sky and as well to skylights – each of these houses has one of these as a main element, yet one is built hovering above the ground while the other burrows into it, like an auger into wood.
The spiral one is the Abalone House in Big Sur, California, designed by architect Thomas Cowen with Rana Creek. The Solo House hovers above the treetops in Chile, and was designed by Pezo Von Ellrichshausen Architects.
It would be really nice to see interior photos of the Abalone house. I looked, but couldn't find any... – GF
