Glass links & glass box roofs for Thornton-Cleveleys: the essentials
Thinking about glass links & glass box roofs in Thornton-Cleveleys? The short answer: frameless glass links joining old and new buildings. The longer answer depends on your roof, which is why we survey before we price.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
We work across Lancashire, including Thornton-Cleveleys, and in neighbouring towns such as Fleetwood and Blackpool. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for glass links & glass box roofs in Thornton-Cleveleys
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.

Glass links & glass box roofs in Thornton-Cleveleys: questions
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Will I need planning permission in Thornton-Cleveleys?
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.
Can you work alongside my builder in Thornton-Cleveleys?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
