Roof lanterns and rooflights for rear extensions in Greater Manchester
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. We design and build rear extensions across Greater Manchester, from Manchester and Oldham to Wigan, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Rear extensions in Greater Manchester gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Greater Manchester has long runs of terraced houses with back yards and alleys, plus 1930s semis further out. Yard extensions on terraces are often single-storey and close to both boundaries.
What does it cost in Greater Manchester?
As a guide, £2,200–£4,500 including VAT. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
What approvals does it need in Greater Manchester?
New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.
