How we approach glass links & glass box roofs in Sevenoaks
Glass links & glass box roofs in Sevenoaks means frameless glass links joining old and new buildings. We cover the TN13 district and the rest of Kent, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
Sevenoaks is around 23 km from Maidstone, and we survey and fit throughout that part of Kent, including the TN13 district.

Do you need permission in Sevenoaks?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about glass links & glass box roofs in Sevenoaks
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Is the survey in Sevenoaks free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Sevenoaks?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
