WOW - this shed is incredible!  It arrived in 4 large boxes and honestly we were worried because the boxes were in rough shape when they were delivered. However all the parts were there and there was no damage.  This took 2 of us about 8 hours total to assemble.  Instructions were easy to follow, and the shed is very sturdy and heavy resin (my manufacturing manager husband was very impressed with the quality!).  We installed on top of slate pavers and it is not moving anywhere.  Plus, the design is perfect and exactly what we were looking for!
