What do glass links & glass box roofs in Egham involve?
Our glass links & glass box roofs service in Egham covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of glass links & glass box roofs for joining a period house to a new extension or annexe.
We work across Surrey, including Egham, and in neighbouring towns such as Staines and Ashford, Surrey. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Egham?
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.
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. 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.

Glass links & glass box roofs in Egham: questions
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 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.
Can you work alongside my builder in Egham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Egham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
