I'm getting a bit closer to finalising the plans for the lean-to greenhouse that's going at the back of the allotment - East facing, on the base of an old Anderson shelter and a little beyond that. Happily, the foundation and concrete path still remain from this.
The plan is to use all the recycled materials I can get my hands on. So far;
- Bricks - hundreds salvaged from around and about
- Glass - about 100 panes (maybe 40cm x 30cm) salvaged from allotment (original greenhouse long gone)
- End door - old hardwood glass door salvaged from skip
- Greenhouse-temp water - old guttering found and galvanised barrel salvaged with plinth
The roof is the area I could do with advice on. Building control (other half) is requesting a glass roof, but to be honest I think that's beyond my skills and would be quite costly, which I'm trying to avoid. I'm edging towards using clear PVC corrugated sheeting, which is pretty cheap if I can't find any in a skip somewhere. Polycarbonate is also an option, but it's quite expensive.
Has anybody used clear PVC corrugate successfully for a greenhouse roof? The front will be done in salvaged glass panes (which is going to be a pain, but at least they'll be used) in three banks between the lintels.
I haven't quite worked out ventilation yet. I'm hoping to find some old windows that I can install in either end.
