Living two people in a tiny house, and having only a bedroom-sized office in said house, thoughts often turn to dreams of an additional structure to hold all the business of business*. One option: the Summerwood Urban Studio, starting at $4195.
Bored with the stock options they offer? You can design your own, right down to the siding and roof materials. I'm partial to cedar siding and metal roofing -- blue, I think.
*Hub's office [for he works at home too] is in the garage. Use every inch, that's our philosophy!
