Glass links & glass box roofs for Coleraine: the essentials
Thinking about glass links & glass box roofs in Coleraine? The short answer: frameless glass links joining old and new buildings. The longer answer depends on your roof, which is why we survey before we price.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Think of glass links & glass box roofs for listed and period buildings where the old wall should stay visible.
We work across County Londonderry, including Coleraine, and in neighbouring towns such as Limavady and Ballymena. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Coleraine?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. Listed buildings also need listed building consent from the council.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Glass links & glass box roofs in Coleraine: 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.
Will I need planning permission in Coleraine?
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall.
Can you work alongside my builder in Coleraine?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
