I am in the process of buying a semi. However the searches have come back and the adjoining neighbours have had planning permission approved for a 2 storey rear extension. 5m out from ground floor and 3.5m projecting out from 1st floor. I’m not too bothered about size of ground floor one as was planning on eventually doing the same in a couple of years. It’s the first floor one I have a problem with as the garden is north west facing and the extension is on west side so would affect sunlight coming into back bedroom. I’m so confused over what to do. Would the size of the extension really cause that much of a problem? Anyone had similar experiences with size of neighbours extensions?
