I'm a stranger to this stuff so excuse ignorance/naievty. We're mid terrace and considering a dormer loft conversion. The problem is that our neighbour to one side has already built their own dormer extension right up to the boundary line (mid chimney breast). The question is can I build off their flank wall or is it necessary/desirable to leave a gap? Aesthetically I think I'd prefer a bit of space, but don't want to lose too much floorspace. Bit cross they've built right up to the boundary line...lesson learned. Hope that makes sense and welcome any advice.
