Extensions in and around Irvine
We cover Irvine and the postcode districts KA11, KA12. The same team covers Kilwinning (3 miles), Troon (5 miles), Saltcoats (5 miles), Kilmarnock (6 miles), all within easy reach.
Just over the Renfrewshire and Inverclyde border, Johnstone is about 15 miles away. 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 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.
In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.

Questions answered
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.
Will my neighbours in Irvine 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.
Who do I contract with in Irvine?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
