Hi! I need to buy a mini lean-to greenhouse for my frost tender plants. They're in a plastic one at the moment, but I know it won't be up to the job of keeping them alive over a harsh, damp winter.

I'd like a fully enclosed one, (mine has a gap at the bottom,) and aluminium is preferred, (although I'll consider hardwood.) I don't mind if it needs some cosmetic work doing to it, as long as it keeps out the cold and the damp.

Measurements of the unit I'd like; 40" width by 88" height (or at least 35" width by 68" height).

Hope someone can help me! Thank you!
