How we approach glass links & glass box roofs in Holyhead
Glass links & glass box roofs in Holyhead means frameless glass links joining old and new buildings. We cover the LL65 district and the rest of Gwynedd, with a survey before any price is fixed.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. In Holyhead, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.

Do you need permission in Holyhead?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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.
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 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.
Is the survey in Holyhead free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Holyhead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
