How we approach glass links & glass box roofs in Pwllheli
For Pwllheli homes and buildings we offer glass links & glass box roofs: frameless glass links joining old and new buildings. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
Neighbouring towns include Porthmadog (19 km) and Caernarfon (30 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Pwllheli
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.

Glass links & glass box roofs in Pwllheli: questions
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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.
Can you work alongside my builder in Pwllheli?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Pwllheli free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
