Neighbours extension plans

[longdistanceclaraclara]

New NDN have put in for planning for an extension. Fair enough. Out the back under permitted development. They have just put in for planning for a hip to gable extension and a dormer. The hip to gable, fine. Doesn't affect anyone else apart from ruing the side elevation. The dormer will have a huge effect on us, our bedroom is in our loft conversion (we are mid terrace, simple conversion), and massively block our light so I'm going to object to the dormer.

The planning documents mention removal of the chimney stack. We share a chimney stack, so does that mean they'll remove the whole thing or remove their 'half'. How does that work?

IABU - just let them get on with it
IANBU - to want to maintain right to light to my bedroom

Honestly, I’d have a chat with them about adding a dormer to mine at the same time. It’ll add to your property and solve the light issue. Expensive maybe but worth it.

You could oppose but you’ll be in for a stressful time, especially if other houses have done it.
Good luck whatever you decide.

I’d check for the removal of the stack but if it’s gone through planning they will have to be upto building regs so should be ok

right to light can be a difficult one if you built a wall 10 inches away directly opposite a window that is blocking the light

an adjacent domer may cast a shadow but there will still be natural light

Definitely speak to them & ask that they arrange (& pay for) a party wall surveyor. They will make sure your property isn't impacted by their works on the party wall - meaning your half of chimney stack.
