I have planning permission for a 2 holiday cabins on my land and need to start the build within the 3 year time limit. However, I want to do the minimum possible amount of work to satisfy the requirement, as I have no intention of completing the build at this time, but want to preserve the permission. Local council say this is fine in principle but are very vague about what constitutes a 'start'.
Would it be ok to just dig the drainage, for example? I'd prefer not to have to lay foundations, because then I would be left looking at ugly concrete footings.
