Neighbours side window

yaskarasan

The house next door to us has an extension, which was already there when we moved into the house. The fence between our gardens starts at the end of that extension. On the side of the extension there is a window which faces our patio it is a long frosted glass window 3 altogether We also want to have a kitchen extension however Would we be okay to build an extension that’s the same length and height as theirs which would cover or block their window facing our garden/patio once the extension is complete. See the pic attached which I took from my kitchen.

Would you be happy if the neighbours blocked your window?

Would it fall under permitted development?

they took a risk in putting their window in that position, There was always the chance you could put tall plants against it, before you even consider your potential extension.

You should not experience any issues with the Planning decision. If it’s PD, then even better. If it needs formal Planning, the LPA ‘may’ asses the impact of your proposals on their extension/windows. However, the windows are already frosted so bring in limited light as it is. You could also erect a 2m high fence under PD and that too would impact those windows. I assume they also have windows to the rear and if that’s the case, those side windows are secondary anyway.

Obviously the neighbour may not be too happy about it but as @silvercar said, that is the risk they took when they built the extension.

I think after 20 years they gain right to light, don't quote me me on that.

If they have another source of light in that room right to light will be irrelevant I think. I can’t imagine a window of that size would offer very much light anyway. I can’t see many issues with getting planning or building approval, even if they objected. I wouldn’t be happy if I were them, but that’s the risk you take when putting windows on the boundary line.
