I live in a terraced house. The attached neighbour has a large full width ground floor rear extension which is a bit of an eyesore and has a significant negative impact on our property. There is no record of the extension on the local authority planning portal, and I am pretty sure it would not be allowed under current planning rules. However, since it has been there a while (I would guess 20-30 years) we've always assumed we are stuck with it.
The house in question has recently sold to new owners and they're planning some significant reburbishment, likely to include demolishing the existing extension and rebuilding a new one in its place. Does anyone know what the rules are in this case? We would like to ensure any replacement extension is smaller and that the design has less impact on our property. Does the size and shape of the existing extension influence what the neighbours can replace it with i.e. is there an assumption a like for like replacement would be allowed? If we wanted to object on the grounds of unacceptable impact to our property (e.g. light, sight lines), does the fact that there is a existing extension weaken our case?
