Working in Ayr
Postcode districts we cover around Ayr include KA7, KA8, KA9. We also work in nearby Troon (6 miles), Irvine (11 miles), Kilmarnock (12 miles), Kilwinning (13 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.

Planning and approvals in Ayr
In Scotland the questions are whether the extension falls within householder permitted development (Classes 1A to 1D) or needs planning permission from the council, and the building warrant, which is required before construction begins and is followed by a completion certificate.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.

Common questions in Ayr
How long does this take for a Ayr home?
2–6 weeks for drawings, depending on the council and the complexity of the project.
Do I need building regulations approval in Ayr?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Will my neighbours in Ayr 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.
How much do extension plans cost?
Our design packs range from about £1,150 to £5,400 including VAT, from planning drawings only to a full pack with building regulations drawings, structural calculations and 3D views. Council fees are separate.
Do I need an architect?
Not necessarily. For most extensions an experienced designer or architectural technologist is enough. For listed buildings or complex sites an architect’s input can help.
