We have a small garden and there's only 1 place it can go and we'd probably have to get rid of the shed- have to convince dh first. We could go with one of those lean to ones although the shed is diplapidated. Or go for a bigger one and bin the shed.
I've seen 2 kinds that i like. One is for about £300 for a wooden frame one. The other is those hexagonal ones in green - on eBay second hand. The only thing id worry about is the glass and accidents with the kids - more that it would hurt them than the damage iyswim.
Also our garden is north facing and the greenhouse woul have to go fairly close to the house. It would get enough sun in the summer as the sun is high but I'd worry about spring time. Any thoughts?
Also if we were to get rid of the shed, what about replacing it with a potting shed? Would that double up as a greenhouse? I'd want to grow tomatoes and such. I tried growing them outdoors last year - along with a lot of other things - and I don't think the soil is good enough and I think it's too wet.
