What do glass links & glass box roofs in Brecon involve?
Our glass links & glass box roofs service in Brecon covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
Brecon is around 64 km from Newtown, and we survey and fit throughout that part of Powys, including the LD3 district.

Planning, building control and Brecon
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.
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.

Glass links & glass box roofs in Brecon: questions
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Will I need planning permission in Brecon?
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.
