What we take care of
- Planning drawings that show the glass detail
- Steel or glass beams and slim-frame glazing
- Drainage details for frameless roofs
- Solar-control and low-energy glass specification
- Design with specialist glazing input
Solar gain is the risk. We specify solar-control glass, plan for opening vents or sliding panels, and avoid fully glazed roofs on south-facing extensions unless shading is included.
Local to Irvine
Site visits are available across Irvine (KA11, KA12). We also work in nearby Kilwinning (3 miles), Troon (5 miles), Saltcoats (5 miles), Kilmarnock (6 miles).
Johnstone, in Renfrewshire and Inverclyde, is roughly 15 miles from Irvine and also on our list. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Do I need planning permission in Irvine?
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted. Separately, almost every extension needs a building warrant from the council before work starts.
The planning position for a specific Irvine address depends on its history and any designations, which is why we check it at the first visit.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.

Common questions in Irvine
How long does a glass extension take to build in Irvine?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.
Do I need building regulations approval in Irvine?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Do you cover all of Irvine?
Yes. We cover Irvine and the surrounding parts of Ayrshire. Site visits are free and there is no obligation.
How much does a glass extension cost?
Our guide range is about £2,940 to £5,680 per m² including VAT, because structural glass is made to order. A 12 m² standard-spec glass extension is typically £41,000 to £52,000 in Irvine.
Are glass extensions cold in winter?
Modern double or triple glazing with warm-edge spacers and underfloor heating keeps them comfortable. They are not as warm as a solid room, and we explain the trade-off honestly.
