Hi everyone - well I can report that the greenhouse is safely here at Bee Towers. Many thanks to everyone who helped me to prepare for dismantling a greenhouse. I took all the stuff, didn't need all of it, but might have done, so good that it was there. At the last minute, I threw a claw hammer in the box. Didn't really know why, but I have noticed that every job I ever seem to do ends up with me needing a hammer. So I took one.
The glass clips were pretty easy and the glass came away okay - I was tense because I find that kind of thing scary, but it was fine really. While I was doing the glass, the lady who sold me the greenhouse started undoing the structure. I wished I had labelled the structure instead of the glass, which largely turned out to be of uniform size. I was going slowly, but she was faster than me, and because she was having the ground levelled the next day, needed to get on. If we had gone at my pace it would have been a two day job. So am a bit worried about remembering what goes where, but am quite good at that sort of thing, and did take pictures, so hopefully it will be okay. The nuts and bolts were all in good condition, and we have saved as many bits as we can - can probably get extras for any losses.
The killer came with the base. It was held down by the most enormous tent pegs I have ever seen - great rusting iron things over a foot long, and buried by mud and in one area, some amateur concreting. Fortunately, my claw hammer got the pegs up slightly, and the owner's crowbar did the rest. Therefore, I would recommend in addition to the shopping list of stuff suggested by forum members, a hammer and a crowbar!
It took all afternoon. The long sections of the base (10 foot) only just got into the Zafira with all the seats down and some packing material protecting the windscreen. It was a matter of millimeters. And I could only transport one at once - thank goodness the greenhouse was local.
I haven't unpacked the car - will do the school run in the other one tomorrow morning. Have treated myself to some white wine in a very large glass this evening.
I won't show pictures of the greenhouse in situ as I didn't ask the seller's permission, but here, for what it's worth, is the site (am in process of clearing it) and the place behind the shed that I am clearing it to.
