Extensions

Building extension in line with neighbor's existing extensiin

Hello! Our neighbor has a single story brick extension within permitted development. It's set back 15cm on to their side, not up to/astride the boundary, so exists on their land only. We plan to build the same size extension in timber frame 15cm on to our side, away from the boundary line, thus leaving a 30cm gap in-between the buildings. As I gather it, this doesn't require a party wall notice, as their wall is on their land so not classed as party. Foundations only need to be 1m for the timber, so I believe we don't need to serve an excavation notice. Can anyone confirm that's ok? We'll have building control here when we start. We would also need to make the gap good somehow - we are thinking of asking our neighbors verbally if they will sign a notice to build/flash the roofs together, but would only entertain it if there was a definite yes there - they've said just to "crack on" in the past but wouldn't sign a document to say it was ok, so here we are - otherwise we'd look at a solution that didn't involve their wall. Any wisdom much appreciated!
