Glass links & glass box roofs in Mitcham: what is involved?
Glass links & glass box roofs in Mitcham means frameless glass links joining old and new buildings. We cover the CR4 district and the rest of Greater London, with a survey before any price is fixed.
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. Think of glass links & glass box roofs for joining a period house to a new extension or annexe.
Mitcham sits about 2 km from Morden and 3 km from Wimbledon, and we cover the whole CR4 postcode district and the roads in between.

Planning, building control and Mitcham
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. 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.
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. 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.
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.
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.
Can you work alongside my builder in Mitcham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Mitcham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
