Glass links & glass box roofs in Dartford: what is involved?
For Dartford homes and buildings we offer glass links & glass box roofs: frameless glass links joining old and new buildings. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of glass links & glass box roofs for listed and period buildings where the old wall should stay visible.
Dartford is around 29 km from Maidstone, and we survey and fit throughout that part of Kent, including the DA1 district.
What you can choose
- Heated glass on some systems
- Frameless sliding or pivot doors
- Structural glass beams and fins
- Solar-control and low-iron glass
- Frameless or slim-framed glass
- Can include frameless doors
- Bright circulation space
Things we check at survey
- Abutments with old masonry need careful weathering
- Thermal performance of large glass areas must be calculated
Do you need permission in Dartford?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

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.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
