Glass links & glass box roofs in Cambridge: what is involved?
Glass links & glass box roofs in Cambridge means frameless glass links joining old and new buildings. We cover the CB1 district and the rest of Cambridgeshire, with a survey before any price is fixed.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
Jobs in Cambridge 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.

Glass links & glass box roofs in Cambridge: questions
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.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
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.
Will I need planning permission in Cambridge?
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.
Is the survey in Cambridge free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
