What do glass links & glass box roofs in Farnham involve?
We handle glass links & glass box roofs across Surrey, including Farnham. 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 South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
Farnham sits about 5 km from Aldershot and 8 km from Fleet, and we cover the whole GU9 postcode district and the roads in between.
What you can choose
- Heated glass on some systems
- Structural glass beams and fins
- Concealed gutters and drainage
- Frameless or slim-framed glass
- Frameless sliding or pivot doors
- Structural glass roof with concealed fixings
- Bright circulation space
What to check first
- Thermal performance of large glass areas must be calculated
- Abutments with old masonry need careful weathering
Do you need permission in Farnham?
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Glass links & glass box roofs in Farnham: questions
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.
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.
Can you work alongside my builder in Farnham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Farnham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
