This review relates to the lean-to wooden greenhouse. Delivery was excellent. No instructions were included, fortunately I'd prevuiously requested them. The instructions leave something to be desired; specifically the advice to treat the green house AFTER is has been erected. I would advise treating it BEFORE whilst it is still in its constituent parts. Having read the instructions it was clear that thoroughly treating it once erected would be impossible so I treated it first. Erecting was fairly straightforwards but for one complete pain in the 'you know where', namely fitting the styrene window panels. Had they been a mere 5mm wider all round (or certainly on the long sides) the better to overlap the timber frames, the advised method of assembly may well have worked. As it was the styrene constantly popped out the frames and, especially once the roof had been put on, was a real trial to replace them, requiring partial dismantling. Eventually managed it, but at the first hint of significant wind two panels popped out again. It's clear the arrangement for installing the styrene will require considerable amendment if this issue is not to recur repeatedly, a problem which may well have been averted with bigger panels that allowed a greater overlap on the wooden framing. Having said all of that, I was pleased with it when I finished building it, and I'll be pleased with it when I've found a way of satisfactorily ensuring the styrene stays in place. It fits the available space perfectly and will provide the space I need to bring on a few plants.
