How we approach glass links & glass box roofs in Littlehampton
We handle glass links & glass box roofs across West Sussex, including Littlehampton. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
Neighbouring towns include Bognor Regis (10 km) and Worthing (12 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Littlehampton?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Glass links & glass box roofs in Littlehampton: questions
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Do I need to be at home for the survey in Littlehampton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Littlehampton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
