Do I need planning permission in Largs?
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 Largs 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.

Home office extension questions answered
Do you cover all of Largs?
Yes. We cover Largs and the surrounding parts of Ayrshire. Site visits are free and there is no obligation.
Do I need building regulations approval in Largs?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
How long does a home office extension take to build in Largs?
On site, typically 8 to 12 weeks once approvals are in place. Before that, allow 4–10 weeks design and approvals.
How much does a home office extension cost?
Our guide range is about £1,810 to £3,330 per m² including VAT. An 11 m² standard-spec office is typically £23,000 to £29,500 in Largs.
Can I claim the cost against tax?
Building work on your home is not normally an allowable business expense, and claiming it can have capital gains tax effects. Speak to an accountant before assuming any tax relief.
