What a planning application involves

This service suits you if you want your two-storey extension to go through planning with the best chance of approval. You get a check of your house's planning history, permitted development rights and local design guidance, a design shaped around them, the application prepared and submitted, and someone to deal with the planning officer's questions. We cannot promise an outcome, but we design to give the application a fair chance.

Across Ayrshire we cover Kilmarnock (KA1), Ayr (KA6), Irvine (KA11), Kilwinning (KA13), Troon (KA10) and Prestwick (KA8), plus the smaller places around them.

Fees

Planning drawings are a guide of £2,000–£3,500, priced in writing before the design stage starts. Householder planning application: £371.

Rules in Scotland

In Scotland, a householder planning application costs £371, and councils have two months to decide. Class 1B permitted development needs 10 m to every boundary, so most two-storey extensions need an application. Planning permission is separate from the building warrant, which is also needed before work starts.

Approval in Scotland: Householder planning application: £371. Councils have two months to decide a local planning application.

Building standards: A building warrant from the council's building standards service before work starts, and a completion certificate at the end. Scotland uses its own Technical Handbooks.

There is no Party Wall Act in Scotland. Shared walls and boundaries are governed by title deeds and common law, so we speak to neighbours early and record the condition of shared structures.

Getting the design right

A complete application

Applications that are missing drawings, the right fee or a certificate of ownership are not validated, and the decision clock does not start. We check the council's validation list so the application is complete on day one.

Neighbours' light and privacy

The main concerns on a two-storey extension are usually loss of light, outlook and privacy for neighbours. We test the design against nearby windows and gardens, and adjust depth, roof shape or window positions before submitting.
