Glass links & glass box roofs in Streatham: what is involved?
We handle glass links & glass box roofs across Greater London, including Streatham. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
From Streatham to Balham, Clapham and Mitcham, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Streatham
- Concealed gutters and drainage
- Structural glass beams and fins
- Heated glass on some systems
- Solar-control and low-iron glass
- Frameless or slim-framed glass
- Designed around the existing building

Things we check at survey
- Structural calculations are part of the design

Consents for glass links & glass box roofs in Streatham
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. 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.

Common questions
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.
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.
