I have a fairly old ground floor kitchen extension at the back of the house. My neighbour wishes to build a similar extension and wants to use the adjoining side wall of my extension as part of this work.

He has vaguely mentioned:
"It (the shared wall) will be one side of the new roof support"
"We don't need to put up any new brickwork for sound/heat insulation, we'll just skim it on our side"
"There can't be any air bricks in it, it's a side wall"
"Our foundations are bound to be lower than yours so they won't create any risk of damage to the wall"

So who should I ask for professional advice about what I should or should not agree to? Would this be a surveyor, structural engineer, architect, builder? And what detailed information should I ask my neighbour's builder to supply? (I'm confident that they are NOT getting an architect or surveyor involved).

any help much appreciated

I'm based in North London BTW

Hi sadjonvee,
This sounds like a disaster waiting to happen.
Even if your neighbours extension is permitted development ie it will not need planning permission they will still have to get building regulations approval. Your local Building Control Department will have to be notified before work starts.
There are so many pitfalls here I suggest you talk to the BR dept and make sure they are involved before work starts.

Thanks Stoneyboy

Sorry took so long to reply - been away for a bit. I've got an appointment to go and see someone at the local council to discuss this so hopefully will be able to get it under control shortly! Thanks for your advice
cheers
