Glass links & glass box roofs for Swansea: the essentials
Thinking about glass links & glass box roofs in Swansea? 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.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
Swansea is the main town we list in West Glamorgan; we also cover nearby Briton Ferry and Gorseinon.

Consents for glass links & glass box roofs in Swansea
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.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
Read the planning permission guide before you commit to a design.

Questions about glass links & glass box roofs in Swansea
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.
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Can you work alongside my builder in Swansea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Swansea free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
