Glass links & glass box roofs in Helensburgh means frameless glass links joining old and new buildings. We cover the G84 district and other parts of Argyll and Bute, with a survey before any price is fixed.

We cover all of Helensburgh and the G84 district, and nearby Greenock and Gourock.

Consents for glass links & glass box roofs in Helensburgh
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Listed buildings need listed building consent where the work affects their character.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 3.3 W/m²K. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
Read the planning permission guide before you commit to a design.

Common questions
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
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.
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.
Can you work alongside my builder in Helensburgh?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Helensburgh?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
