This began as a small retreat house, in two halves connected by a central skylit entry, with full-height sliding doors on two sides and blank walls on the entry facades. But, then I got to thinking, and decided to put it on stilts up in the air, like the fire lookout towers that dot the American West’s forests. Obviously, this necessitates a staircase, which I suggest making a conical spiral. To increase livable space in what would be an otherwise stuffy cabin, the entire steel structure has been wrapped to create an over-sized screened porch. While I started with a butterfly roof and tried out a hip roof, I find the dichotomy of the butterfly against the spindly supports to be rather compelling.
