We have been notified that one of the bungalows at the back of our garden wants to add a dormer extension so they can put a room in the loft space. I don't have a huge problem with the dormer as the angle of the house means it isn't majorly impacting on us. The main issue we have is they want to put a window in the rear so our current very private garden would then be overlooked. As they are all bungalows we don't have first floor windows looking over at us. One of the big selling points to us was the private garden - has anyone objected to this before and what was the outcome? Is it worth objecting to them using the loft space too as I am concerned this would set a precedent and we'd see bungalows turned into houses, not sure I can do much about that of course in the long run. I also don't want to be a horrible neighbour but willing to stand our ground on the window. Any advice greatly appreciated!
