Glass links & glass box roofs in Dulwich: what is involved?
We handle glass links & glass box roofs across Greater London, including Dulwich. 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 London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Dulwich, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Dulwich sits about 2 km from Brixton and 3 km from Peckham, and we cover the whole SE21 postcode district and the roads in between.
What you can choose
- Heated glass on some systems
- Frameless or slim-framed glass
- Solar-control and low-iron glass
- Concealed gutters and drainage
- Structural glass beams and fins
- Visually light connection between buildings
- Keeps period walls on show
What to check first
- Listed building consent or planning permission is commonly needed
- Thermal performance of large glass areas must be calculated
Do you need permission in Dulwich?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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. 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.

Questions about glass links & glass box roofs in Dulwich
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
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.
Do I need to be at home for the survey in Dulwich?
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 Dulwich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
