What do glass links & glass box roofs in Belper involve?
We handle glass links & glass box roofs across Derbyshire, including Belper. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
We work across Derbyshire, including Belper, and in neighbouring towns such as Ripley and Heanor. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Belper?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about glass links & glass box roofs in Belper
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.
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.
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.

Yes. We survey and fit glass links & glass box roofs in Belper and across Derbyshire. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Belper?
