Glass links & glass box roofs for Morden: the essentials
We handle glass links & glass box roofs across Greater London, including Morden. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Morden, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Jobs in Morden are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Concealed gutters and drainage
- Structural glass beams and fins
- Heated glass on some systems
- Frameless or slim-framed glass
- Frameless sliding or pivot doors
- Visually light connection between buildings

Before you order: points to check
- Thermal performance of large glass areas must be calculated
- Abutments with old masonry need careful weathering
Planning, building control and Morden
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.
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. 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.

Glass links & glass box roofs in Morden: questions
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
How do I book a survey in Morden?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Morden?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
