Our neighbour (in a row of terraced houses) has applied for planning permission for a outbuilding at the end of their garden, 3m high and 4m deep. It will be as wide as their garden and just inches from ours.
It won't impact our light or privacy (no windows overlooking our garden) but given it's right next to the boundary and its height/depth, it's going to be an eyesore and change the character of our garden and other neighbours. We're in a conservation area but not sure the back of the houses is covered by that. Due to the way the light falls, we have our patio at the end of the garden, the other side of the fence from the proposed building. Instead of looking at the sky from our patio, we'll soon be looking at a brick wall!
Does anyone know of any reasonable grounds we can use to object? Assuming they'll get permission but it would be great if the pemission comes with a requirement for it to be smaller (lower height/depth).
Thanks!
