Straightens a sloping side roof on semi-detached and end-of-terrace houses.
Near-vertical rear roof slope for the most space; usually needs planning.
Windows set into the existing roof slope with the least structural change.
Many lofts fall under permitted development: up to 40 m³ of extra roof space for terraced houses and 50 m³ for semi-detached and detached houses, with nothing added at the front roof slope facing the road. Mansards and front dormers usually need planning permission.
Floor structure, a safe escape route in a fire, the new staircase, insulation and sound separation. Building control signs these off before completion.
