What do glass links & glass box roofs in Islington involve?
We handle glass links & glass box roofs across Greater London, including Islington. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
Jobs in Islington are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Heated glass on some systems
- Solar-control and low-iron glass
- Frameless sliding or pivot doors
- Structural glass beams and fins
- Frameless or slim-framed glass
- Visually light connection between buildings
- Bright circulation space
Before you order: points to check
- Structural calculations are part of the design
- Abutments with old masonry need careful weathering
Do you need permission in Islington?
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. 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.

Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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.
