Architectural Glazing in North Wales
Glass extensions, slimline sliding doors, glass links and bespoke steel glazing across North Wales. We have completed work in Wales, we are twenty-nine miles from Wrexham, and — importantly — we understand that Welsh planning is not the English system with different signage.
Welsh Planning Is Not English Planning
This is the single most common thing English glazing companies get wrong about North Wales, and it costs their clients time and money. Planning in Wales is a devolved matter. It runs on Planning Policy Wales and the accompanying Technical Advice Notes, not the English National Planning Policy Framework, and permitted development rights in Wales are set out under separate Welsh legislation with genuinely different thresholds.
In practice that means an extension that would sail through as permitted development in Cheshire may not in Flintshire, and advice copied from an English website can be simply wrong. If a supplier tells you the English rules apply, they have not done this before.
There are six local planning authorities across North Wales — Wrexham, Flintshire, Denbighshire, Conwy, Gwynedd and the Isle of Anglesey — plus Eryri National Park Authority, which is the planning authority in its own right for everything inside the park boundary. Note that Eryri is the name now used for what was Snowdonia.

Our Work in Wales
We completed a scheme of slimline sliding doors and a bespoke glass balustrade on a Welsh property — the kind of project that suits the landscape here, where the reason for glazing is almost always the view. We have also worked extensively on stone farmhouses, barns and listed rural buildings across the North West, which is closely comparable to the building stock through Denbighshire, the Clwydian Range and rural Conwy.
North Wales throws up two very distinct briefs. Coastal properties at Llandudno, Colwyn Bay, Abersoch and along the Anglesey shore, where the priority is the sea view and the constraint is exposure. And inland stone properties — farmhouses, cottages and barn conversions — where the priority is light and the constraint is usually planning.

National Parks, National Landscapes and Coastal Sites
Alongside the six local authorities, Eryri National Park Authority handles planning inside the park, and its policies on new development and visual impact are considerably more restrictive than those of the surrounding councils. Assume nothing is permitted development inside the park boundary until it is confirmed.
There are also three National Landscapes, previously called Areas of Outstanding Natural Beauty: the Clwydian Range and Dee Valley, Anglesey, and the Llŷn. Inside these, the visual impact of any extension carries unusual weight — which is precisely where a lightweight, largely transparent structure argues better than the equivalent volume in stone or render.
Coastal sites bring their own considerations. Salt-laden air on the Conwy and Anglesey coasts attacks fixings, seals and coatings, so we specify marine-grade fixings and appropriate coating systems for exposed elevations. Some shoreline sites also raise flood-risk questions, which is better identified at survey stage than after drawings are paid for.
Many rural Welsh properties are listed or sit within a listed curtilage, and stone buildings that have stood for two centuries have moved. We measure every opening on site rather than working from a drawing.
What Affects the Cost?
Every project is priced individually, but the things that move the number most are consistent:
- Pane size. Cost per square metre rises sharply once panels exceed what two people can lift, because you are then into crane hire.
- Coastal specification. Marine-grade fixings and a suitable coating system on an exposed Conwy or Anglesey elevation. Not optional if you want it to last.
- The condition of the opening. On a stone farmhouse or barn, making good the existing structure is frequently a bigger job than the glazing.
- Thermal specification. Exposed upland and coastal sites justify a higher specification of insulated unit than a sheltered suburban plot.
- Access and distance. Wrexham and Flintshire are straightforward from us. The Llŷn and Anglesey are a longer haul and single-track access can complicate a crane lift.
Send us your drawings, or even a photo of the building, and we will give you a realistic budget range before you spend anything.
Architectural Glazing in North Wales — Common Questions
Yes, genuinely different. Planning in Wales is devolved and runs on Planning Policy Wales and its Technical Advice Notes rather than the English framework, and permitted development rights are set out under separate Welsh legislation with different thresholds. Advice copied from an English site can be wrong. We work to the Welsh system.
