The greenhouse arrived in two boxes:  one with panels and the other with aluminum framing and hardware.
Looking at all of the parts was a bit overwhelming at first, but once separated, were all easily identified. 
We decided to create a frame of 2x6 pressure treated lumber, and then attach the Greenhouse to it on a level bed  of paver stones.
The structure took about 12 hrs in all to erect: all parts fit well and looks really nice!
We are at the base of Mt. Shasta,  north of Weed, Ca.
The wind gusts were 40-50 mph last night, and our little (6×10) greenhouse didn't budge!
