I am selling the 20 sided house that I built in Topham, VT ten years ago. The house is almost round and has great southern exposure with lots of windows on the south side. It has a massive central chimney made of old concrete road culvert tiles that holds heat well and distributes it throughout the space. The main timbers for walls, floors and roof are softwood poles harvested locally. The top floor is wide pine boards, with some 24″ boards. The sole source of heat is a woodstove and the water for the clawfoot tub is heated by a gas fired on-demand hot water heater. Water is gravity fed and comes from a spring.
