We’ve built a party wall that straddles the boundary (party wall agreement in place) - neighbour has agreed this on the basis we’re paying to build the wall. There’s a double layer of breeze blocks with insulation in the middle. Builder says the neighbour must render his side, but the wall must be sealed by bitumen or the builder won’t sign their guarantee. It all feels wrong and our neighbour has been tricky at every turn. Any online searches just flag up the party wall Act. Our party wall agreement doesn’t specify what happens to the wall on the adjoining side.
