What do glass links & glass box roofs in Crowthorne involve?
For Crowthorne 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
Crowthorne is around 16 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG45 district.

Consents for glass links & glass box roofs in Crowthorne
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. 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.

Common questions
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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.
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.
Is the survey in Crowthorne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
