1) Garage foundation doesn't look safe?
2) It's right on the boundary. Are they within their rights to do this?
3) Best way to solve it. Build retaining wall and fill with cement to secure the soil underneath existing concrete?
The right of support can also apply to ground (as distinct from a building) that is in danger of collapse as a result of excavation on neighbouring land.Thus a right of support also exists in the case of retaining walls that coincide with a property boundary.
There appears to be no duty of care or right to support issue there, it looks like the OP has not removed anything.
It's the neighbours crappy support building for their own garage, they are the ones that had the duty to ensure that their foundation is well supported.
It would have been better to build a small wall there to ensure the earth under the foundations stays there given the difference in land levels.
Totally the neighbours problem.
OP, you could be neighborly and let them know what its like now and that it may get worse in future.
