Ahhhh. I've loved this house/meditation room since I first saw it in Woodstock Handmade Houses in the '70s. A real thrill to see it again! Thank you@Barbara-Rose Pierre Paul for pointing this site out to me! Merci!
Paul’s Tiny House in the Woods -- "10 x 20 house ..is built on six poles set two feet into the ground, that support the floor and roof. There is no framing in the walls except at the door and the large window. The walls are rigid foam insulation, R21, covered with ½ inch sheetrock and all glued together. The ceiling has R38 fiberglass insulation, and the floor has R19 fiberglass insulation."
