This is the second Lifetime shed that I've purchased and I leveraged that previous knowledge to put this one together. Overall, it is solid construction but I found out after assembly that it had a slight warp such that the doors didn't align flush. I built this shed on a wood platform made of pressure treated 4x6 beams and 3/4inch pressure treated plywood. My friend and I spent two days building the platform and making sure it was plumb square and level at all corners. Once that base was in place we proceeded to build the shed. Took the two of us about 6hrs start to finish to build the shed, only to find out the doors weren't fully aligned. Ended up using wood shims to get the doors aligned by shimming the back left corner of the shed. Still I would recommend it to anyone looking for a good looking shed that is water proof. Perhaps my unit just had a warp in manufacturing.
