A Combination Garage, Shed and Loft Office - This customized version of the Cold Spring Barn was built in Wisconsin from inexpensive, stock pole-barn plans by architect Don Berg. I would make it a loft craft room instead!
DIY Kit House - The folks at Jamaica Cottage Shop offer kit for Vermont cottage. It takes 2 people hours to construct. Interior can be outfitted a number of ways; add sleeping loft for maximum efficiency. (interior not shown)
