Both packages for the greenhouse arrived in a timely manner and were undamaged. The contents were checked and all was in order. I will prefix what I say about the build, by stating that, I built this greenhouse completely by myself and it took 7 hours exactly. The base and main middle section of the greenhouse went well. I would say that the A frame ends of the roof were certainly the most difficult. I also found that the manual was not very clear to follow during these parts. Palram did a good job of marking the frame parts, screws and bolts, etc, and had stickers on the polycarbonate panels, showing which was the front. Hopefully, the longevity of the greenhouse will be better than some other reviews I have read for this model, but then, mine is not fully exposed to the wind as it appears theirs were! Overall, I am very satisfied with this purchase. I am now looking for a suitable heater for the winter!
