I'm having a problem with a current extension we're doing as we went further (less than a meter) beyond what's stipulated in the approved plan. Obviously neighbour complained so council came with a tape measure. The council send a warning letter (not yet an enforcement notice) saying we should alter it in accordance to the plan or submit a retrospective pp.
We've already built quite substantially and altering would mean digging up foundation and walls, removing, resizing then refitting metal roof frame which amounts to almost demolishing the entire build. I am very much in despair then suddenly realised that I actually have two approved planning permissions where the plans look identical except for a couple of doors turned to windows (but same opening positions) and Veluxes in the roof. Both plans (submitted and approved in different years) were approved with the condition that works had to be carried out in complete compliance of the plans and specs however, the first plan doesn't have any measurements in the drawing whereas the second plan which we're currently using, has. Can we revert back to the original approved plans without specific measurements?
I've read a few legal cases online but they refer to commercial development than residential.
Has anyone here has similar experience to ours? Any advise ?
Many thanks.
