My neighbour is building a new extension on the rear which will adjoin our party wall. he has suggested it will be a timber frame single story and as such he doesn't need proper foundations as a concrete slab will suffice.
is that correct and if so should I have any concerns about the slab affecting the party wall which is about 2m high.
TIA
