What do glass links & glass box roofs in Lisburn involve?
We handle glass links & glass box roofs across County Antrim, including Lisburn. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. Glass links & glass box roofs suit listed and period buildings where the old wall should stay visible.
Lisburn sits about 11 km from Belfast and 11 km from Castlereagh, and we cover the whole BT27 postcode district and the roads in between.
Specification options
- Heated glass on some systems
- Concealed gutters and drainage
- Frameless or slim-framed glass

Things we check at survey

Planning and building rules for Lisburn
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. 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. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.

Questions about glass links & glass box roofs in Lisburn
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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.
Do I need to be at home for the survey in Lisburn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Lisburn free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
