Planning and building rules in Northern Ireland
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.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.

Common questions
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.
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.
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 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.
