Roof lanterns and rooflights for rear extensions in the Isle of Wight
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. We design and build rear extensions across the Isle of Wight, from Newport and Ryde to Cowes, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Island and remote addresses in the Isle of Wight are by arrangement: we confirm whether we can take the job, and agree any travel costs, before the first visit.
Rear extensions in the Isle of Wight gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Isle of Wight has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.
What does it cost in the Isle of Wight?
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 Isle of Wight?
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.

Can a rooflight open?
Yes, manually or electrically, with rain sensors.
