What do glass links & glass box roofs in Stevenage involve?
We handle glass links & glass box roofs across Hertfordshire, including Stevenage. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
Stevenage sits about 8 km from Hitchin and 9 km from Letchworth Garden City, and we cover the whole SG1 postcode district and the roads in between.

Do you need permission in Stevenage?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about glass links & glass box roofs in Stevenage
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.
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.
Do I need to be at home for the survey in Stevenage?
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 Stevenage?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
