Roof lanterns and rooflights for rear extensions in Cheshire
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. We design and build rear extensions across Cheshire, from Warrington and Chester to Crewe, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Rear extensions in Cheshire gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Stone and brick terraces are common around Cheshire. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
What does it cost in Cheshire?
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 Cheshire?
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.
