I absolutely love this. Reminds me of an adobe bubble house I saw in an article many years ago. Richard Olsen's Book Handmade Houses Showcases Beautiful and Unusual Homes : Architectural Digest. Probably for my future little house in Europe.
STAIRCASE – one of the most unique circular staircases Ive ever seen. Very rustic, open, and custom. London, England: Medieval staircase displayed at the Victoria and Albert Museum. (Photo by Carol Estes) - House Decorators Collection
