Love this amazing greenhouse.  Assembly was based off pictures. I was missing 1 crucial piece and called the company which was great customer service.  Took about 2 weeks for arrival for missing part. Took almost 5 months for delivery for the whole kit. Assembly was easy on some steps and on some steps, did not make any sense.  A lot of going back to either flip, remove, replace etc. Took me ( Im a 36 year woman) about 3 days of Assembly.  Probably would of taken less time if I had help. The window that opens for ventilation doesnt work ( it just slams shut) Ordered an automatic opener. In the beginning a lot of parts are very flimsy, and unstable but as you build the greenhouse somehow gets sturdy. I recommend mounting the frame down first. Other than that, its an great greenhouse.
