Neighbour wants to build a wall

[£15]

Sorry, just spotted that his garden is higher than yours?
What is currently retaining his land from collapsing into yours? If its going to be a retaining wall then he is legally obliged to support his own land.
As for the height, if it sits wholly on his land then it is measured from ground level his side. However, by the sound of it the idea is to place the wall astride the perceived boundary in which case it could be argued that it could be measured from your side if his land is higher.

As I mentioned above though, as long as your neighbour plays ball and involves you in the process (lots of grovelling and general boot licking) and everything is amicable there is unlikely to be any problems and you'll have a nice maintenance free wall.

Could you expand on this? Is it a national regulation, or vary from council to council?

It's just that the garden behind me is about 1.5-2.0 metres higher than mine and the wall keeping it back has seen better days. If it's their responsibility I'll ask them to have it checked out and repaired as necessary.

There's nothing my my deeds and my Solicitor found nothing to say whos responsibilty the wall is.

A investigation of the position of the boundary is needed because, is it his wall or your wall?
If the wall is holding back his ground, then it could be your wall, or his wall holding back his ground from your property, a very grey area, needs properly sorting, always the chance he could get funny & say it's your wall, & you end up wil a large bill to repair or replace it.

Usually with boundary walls someone will have a right to maintain it & they must excersise that right to prevent the wall from collapsing & it's collasping into their neighbour's property.
