June 23, 20233 yr We are planning to build a single storey extension to the rear of our property, hopefully around 4m out and 3m high. Our house is a 1930s end-of-terrace. Our attached neighbour's house has a half-width extension (constucted 20-30 years ago) built right up to the boundary of our property, extending approx. 3.7m out and 2.5m high. I've been told that it would be best to seek a party wall agreement and build that side of our extension off the existing wall. There are reasons why I'm hesistant, but I understand leaving a gap between the properties isn't ideal either. If we wanted to build completely separately, is there a recommended gap between the buildings? Concerns: Our garden boundaries are not straight out from the house, instead they are a parallelogram, sloped in towards my garden. Because our neighbour's extension has been build straight off their house, this has left a small triangle of their land on our side of the fence. I imagine if I wanted to build on this land it might be complicated? We would want to build up to maximum 3m height - could this be done off the existing wall? If the neighbour wanted to knock down and redevelop their existing extension I guess this could be complicated.
June 23, 20233 yr Do yourself a huge favour and keep your structure independent. You will need party wall agreement for digging footings close to theirs but much simpler than connecting to it.
June 23, 20233 yr Author Thanks @markc, that's definitely the way I'm leaning. Is there a recommended gap between the properties? I guess as long as it's big enough to get someone down there for access & prevent damp that's sufficient?

I guess as long as it's big enough to get someone down there for access & prevent damp that's sufficient? No minimum as far as I know. New build not far from me and I don’t think anyone other than a tiny child would get through the gap, seems stupid.

I guess as long as it's big enough to get someone down there for access & prevent damp that's sufficient? No minimum, but how badly do you need the space? You'd need at least 600mm to erect a narrow scaffold tower or squeeze through with a wheelbarrow. And the roof will normally have an overhang.
