I wanted to build a small tool shed just to keep fishing equipt. and such down by the pond. It ended up being about the size you speak of. After pricing new "shells" of sheds I built my own. With electric, insulation,ac, and heat only cost $2000. Has a small bed, microwave, Direct tv,and a coffee pot. All I need!! It is built much much better than the ones you buy. Might check with a local carpenter if you are not able to build it yourself. Just my thoughts. Good luck
