Glass links & glass box roofs in Welling: what is involved?
We handle glass links & glass box roofs across Greater London, including Welling. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Welling, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Welling sits about 2 km from Bexleyheath and 4 km from Bexley, and we cover the whole DA16 postcode district and the roads in between.
What you can choose
- Frameless sliding or pivot doors
- Structural glass beams and fins
- Frameless or slim-framed glass
- Concealed gutters and drainage
- Heated glass on some systems
- Can include frameless doors
- Designed around the existing building
What to check first
- Listed building consent or planning permission is commonly needed
- Abutments with old masonry need careful weathering
Consents for glass links & glass box roofs in Welling
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Glass links & glass box roofs in Welling: 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 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.
Is the survey in Welling free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Welling?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
