Its not as daft a question as it sounds, having moved into a new house last autumn part of the deal was that I would get a GH in the back garden. There is space for it in the corner next to the shed and a proper concrete / brick base will be built to keep it level and elevated (at 6,6" I need the elevation).
Question is apart from the obvious dimension of the greenhouse how much extra space do I need to allocate when planning etc. Didn't want to build a base only to have to do it again, similarly didn't want to waste 3 ft if I don't need to...
Grateful for any advice.
