Hi all! First post here.
I'm about to take on a plot in my very first allotment and I'm absolutely too excited. Cannot wait. In the meantime we managed to procure a greenhouse on facebook which is in pretty good nick absolutely FREE. It's approximately 6ft x 6ft (picture attached). Feel very lucky. Have been to visit in the evening but didn't really have much time to start dismantling so we are planning on doing that on Wednesday. No broken panes, frame didn't look at all warped, no gaps etc. Feels like I've struck gold!
Anyway onto the question. My allotment (down in gosport), like most, doesn't allow for the use of any concrete, cement, permanent structures etc. Looking across the site you can see a few greenhouse frames without any glass looking extremely sorry for themselves, so I'm guessing it can get pretty windy there. From just glancing around, most of the ones I could see had just been laid on top of the soil.
My current plan is to dig out an area for the perimeter of the frame, maybe an inch or so deep, tamp down the soil good and proper, and lay down some paving slabs. Paving slabs will just have to sit on the soil. On top of that will sit some kind of timber (treated fence posts? used railway sleepers?) and I will fix the bottom of the greenhouse into the timber with screws.
How does that sound in terms of stability and longevity? Is it hopeless? What would be the best timber to use? Should I treat it myself (and what with?) Are the paving slabs a waste of time?
I am a relative beginner when it comes to greenhouses so absolutely any and all advice is welcomed.
Thanks so much!
