Considering buying a house that has a wall in front of it. House is 1960s, wall looks considerably older and continues past the house for quite some way and over a bridge. It's about a foot thick at least and made of old stones, a bit like you'd see on a railway bridge. There is a gap in the wall (looks like it was cut in when the house was built or maybe later) to get into the parking area in front of the house but it isn't very wide and awkward to get in and out of. Had gates at one time but they've been taken off. No parking on the road, all double yellows.
If we could take another 2 ft off the wall to widen the entrance it would be fine but as it is it'd be a nightmare getting in and out several times a day. DH is confident we could just chop a bit off the wall but I'm concerned it doesn't actually belong to the house, and the title deed isn't helpful it just has a line along the boundary but not clear if its in front of or behind the wall.
Has anyone had a similar situation and can offer advice please?
