Frameless structural rooflights for Bangor, Gwynedd: the essentials
For Bangor, Gwynedd homes and buildings we offer frameless structural rooflights: minimal glass rooflights with no visible frame from inside. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Bangor, Gwynedd, as anywhere, frameless structural rooflights are the usual choice for rooms where you want sky without a visible frame.
We cover all of Bangor, Gwynedd and the LL57 district, and nearby Llangefni and Caernarfon.

Do you need permission in Bangor, Gwynedd?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
