Hi Everyone - I'm hoping to purchase a house that has a large retaining wall directly behind it. It's the height of the 2 storey house and directly abuts it at the bottom with a gap increasing towards the top. I think I need it surveying and some guarantees in place about the structure. I haven't had any luck with the normal surveying companies as it seems a bit beyond everyone's experience. I think it would be very hard to survey it right at the back as you can't get to it. But I am no expert at all. Who do I go to? Should I just walk away? Any help appreciated.
