A nice greenhouse when built but assembly is a nightmare. The estimate of one to two hours to assemble with two or three people is a joke. It takes about two hours to unpack, sort and check all the many components before you can start with the base frame. The slots for the bolt heads is a good idea, as you only need a spanner inside to tighten the nuts however to hold the bolt in the slot while trying to join together the fames and tighten the nut is a struggle requiring 3 hands to make it work. Some of the windows were a poor fit and had to be sealed with frame seal to close gaps and I am sure in strong winds they could blow out. I estimate the total time to unpack, check all components, read instructions, fit base (which must be level) and finish assembly took 17 hours of two persons, one a retired motor engineer and one a builder, both experienced tradesman. Unless you are a competent DIYer and have the patience of a saint, dont buy this greenhouse. Not recommended !!

My hubby is over the moon with this

Ordered and delivered when they said it would arrive within 3 days. Instructions comprehensive. Although not a negative it would have been nice at the start of the instructions what tools were required.

Takes a while to put together but looks good

Well delighted with the greenhouse. We concreted the base and sealed the panels fir extra support.
