My house came with a rotted shed that needed to be replaced and I got the Arrow Commander 10' x 20' Storage Building and it has become the best/worst purchase I have ever made. This storage building is beyond roomy and it has become my main housing unit. The construction of this building is extremely solid and has stood up to several harsh Chicago winters without any changes in its physical appearance. I was amazed that the roof stood up to 20 inches of snow this past winter and it didn't collapse or bend. The downside to this storage building is that during the winter it seems to be colder inside than outside and the exact opposite during the summer. The reason why I say this unit is a bad purchase is because it is so spacious that I have been buying more things than I need just because I can accommodate more things. I have two lawn mowers, a snow blower, a workstation, a car, and a plethora of random tools stored with room to spare. I would definitely recommend the Arrow Commander 10' x 20' Storage Building because it can almost take the place of a garage and doesn't require the same amount of upkeep.
