    Spectacular value

    Posted by Steve on 15th Nov 2022

    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!

    Shed review

    Posted by Adam on 27th Jun 2020

    First: The customer service was outstanding! Because I'm pretty inexperienced with this sort of thing, I emailed repeatedly with questions and always received fast and helpful replies, often with useful illustrations. The construction is as easy as promised. Everything made sense and went together easily. Instructions say two people can do it. Probably true, but with limited experience and local temperatures in the high 80s, we found it helpful to have a third pair of hands sometimes -- just for hauling lumber and especially for raising the gables. The shed looks terrific and is very tight and solid. Highly satisfied.
