Roof lanterns and rooflights for rear extensions in Gloucestershire

Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. We design and build rear extensions across Gloucestershire, from Gloucester and Cheltenham to Stroud, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.

Rear extensions in Gloucestershire gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Gloucestershire has Victorian terraces nearer the centre and post-war semis on the edges. Sloping gardens are frequent, which affects floor levels and steps down to the patio.

What does it cost in Gloucestershire?

As a guide, £2,200–£4,500 including VAT. These are guide ranges; the written quote after the survey is the figure that counts.

What approvals does it need in Gloucestershire?

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.
