Glass links & glass box roofs for Colchester: the essentials
We handle glass links & glass box roofs across Essex, including Colchester. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Colchester, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Neighbouring towns include Sudbury (20 km) and Clacton-on-Sea (21 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Colchester
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Glass links & glass box roofs in Colchester: questions
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Is the survey in Colchester free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Colchester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
