I managed to construct this shed once spring arrived for us in Alberta having recieved it in December. The instructions were very complex and vague at points which made it sometimes challenging. What was most difficult was dealing with the poor machining and holes that were not situated in the right place. There are areas a hand cannot access a screw to place on protectors, the door didn't fit properly and the lock holes were completely in the wrong place. There are two holes in the door panel for some reason which means the shed is not water tight, so to speak. There is no way a single person could assemble this and you would 100% need a power tool. Really, this product should have been half the price it is currently selling for.
