Roof lanterns and rooflights for rear extensions in the West Midlands
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. Rear extensions in the West Midlands: we cover 33 towns including Birmingham, Coventry and Wolverhampton, with design, approvals and the build under one contract.
Rear extensions in the West Midlands gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Red-brick terraces and 1930s semis make up much of the West Midlands. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
What does it cost in the West Midlands?
As a guide, £2,200–£4,500 including VAT. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
What approvals does it need in the West Midlands?
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.
