Want to expand your home, add an in-yard office or small cabin, but light on cash? Add usable, stylish space to your home with one of these small footprint sustainable structures from San Francisco’s Modern Cabana.  These tiny buildings feature:  optimized framing, FSC-certified lumber and siding, bamboo flooring, recycled denim insulation and a waste-reducing manufacturing process.

Most of these prefabricated base units are single room, without bathroom. You can customize the larger models to include a bathroom as well as room dividers.  Those with building experience and a few friends can probably put up one of these in a few days.

It’s recommended that you mount the structure on cement piers.  And the roof, as shipped, is not suitable for supporting heavy snow loads.  Sizes range from 10′ x 12′ to 12′ x 25′ and basic kits prices range from $500 for a dog house, to $31,000 for the largest model (you customize doors, windows, etc. and accessorize from there).  Installation and shipping are extra.
