Glass links & glass box roofs for Dunstable: the essentials
Thinking about glass links & glass box roofs in Dunstable? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Dunstable, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Neighbouring towns include Luton (7 km) and Leighton Buzzard (10 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Dunstable
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
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 do I book a survey in Dunstable?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Dunstable free?
