Glass links & glass box roofs in Dolgellau: what is involved?
Thinking about glass links & glass box roofs in Dolgellau? 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.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Dolgellau, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Dolgellau is around 56 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL40 district.

Consents for glass links & glass box roofs in Dolgellau
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
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.

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.
