Glass links & glass box roofs in Gorseinon: what is involved?
Glass links & glass box roofs in Gorseinon means frameless glass links joining old and new buildings. We cover the SA4 district and the rest of West Glamorgan, with a survey before any price is fixed.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for glass links & glass box roofs include joining a period house to a new extension or annexe.
We work across West Glamorgan, including Gorseinon, and in neighbouring towns such as Llanelli and Swansea. Access, parking and how the glass reaches the roof are all checked at the survey.

- Solar-control and low-iron glass
- Structural glass beams and fins
- Frameless or slim-framed glass
- Heated glass on some systems
- Frameless sliding or pivot doors
- Visually light connection between buildings

Things we check at survey

Consents for glass links & glass box roofs in Gorseinon
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about glass links & glass box roofs in Gorseinon
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.
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.
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 Gorseinon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Gorseinon?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites.
