Glass links & glass box roofs for Carlisle: the essentials
For Carlisle 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Carlisle, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
We cover all of Carlisle and the CA1 district, and nearby Penrith and Keswick.

Planning, building control and Carlisle
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.

Glass links & glass box roofs in Carlisle: 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.
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 you work alongside my builder in Carlisle?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Carlisle free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
