Glass links & glass box roofs in Biggleswade: what is involved?
We handle glass links & glass box roofs across Bedfordshire, including Biggleswade. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of glass links & glass box roofs for listed and period buildings where the old wall should stay visible.
Biggleswade sits about 5 km from Sandy and 12 km from Letchworth Garden City, and we cover the whole SG18 postcode district and the roads in between.

Planning and building rules for Biggleswade
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about glass links & glass box roofs in Biggleswade
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Can you work alongside my builder in Biggleswade?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
