What is included
- Whole-house energy calculations where needed
- Steel or glass beams and slim-frame glazing
- Planning drawings that show the glass detail

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.

Extensions in and around Erskine
Across PA8, we can visit, measure and advise. Nearby, we also take on projects in Renfrew (3 miles), Paisley (5 miles), Johnstone (6 miles), Barrhead (7 miles).
For homes towards Dunbartonshire, Clydebank is around 2 miles away. Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.
Will the council need to approve it?
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
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.

Build and sign-off

Common questions in Erskine
Do I need building regulations approval in Erskine?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Will my neighbours in Erskine be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Do you cover all of Erskine?
Yes. We cover Erskine and the surrounding parts of Renfrewshire and Inverclyde. 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 Erskine.
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.
