Thanks noseall, i thought as much, i'm just debating how much 'appearance' matters on a 1950's semi. I'd prefer a pitched roof but if the difference is in the 1000's i look a at a flat one.
Hi,
planning an extension on back of the house, roughly how much more would a pitched roof with sky light be, as opposed to a flat roof? 5.6m wide*3m.
