I'm blown away by this shed that I'm using as a home office. Took about 3 weeks to arrive in CA. It was a blast to install, with the main body taking about a day. I added a hardwood floor and a layer on the roof with insulation (you can't insulate the walls). I added the extra double window, although it needed adjustments to the supporting boards to fit properly. Door is very nice, but the wood is very green, and the resulting warp is drafty and requires some insulation (on that note...you must build IMMEDIATELY upon receipt because the wood is so green). The shed is HUGE and high quality. I may have the nicest office in the company now, and at an amazing price!
