I have no idea how well this will hold up, but 4 of us finally got our heads together and figured out the directions.  There could be much better instructions.  An audio CD to go along with the instructions might help those of us with written direction deficiencies.   We watched the short instructional film on youtube several times, but it did not prepare us for the special challenges of this larger shed.  Still, once the floor was built it took us about 9 hours.  I hope it holds up.  Be careful not to strip any screws.  

Pros: Looks pretty nice
Cons: Challenges with set up instructions
