Covering Irvine
Our survey diary covers Irvine, including KA11, KA12. Neighbouring towns we cover include Kilwinning (3 miles), Troon (5 miles), Saltcoats (5 miles), Kilmarnock (6 miles).
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.
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.
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.
Applications are decided by your council as planning authority.

Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.

The price is fixed in writing once the design is settled, with a clear programme and payment stages.
Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Bungalow extension questions answered
How long does a bungalow extension take to build in Irvine?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
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.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Irvine, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,720 to £3,330 per m² including VAT. Going upwards is priced after a structural survey.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
