Planning rules that apply in Nairn
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. Separately, almost every extension needs a building warrant from the council before work starts.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.
Who an annexe extension suits

Do you cover all of Nairn?
Yes. We cover Nairn and the surrounding parts of Highlands and Islands. Site visits are free and there is no obligation.
Do I need building regulations approval in Nairn?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
How much does an annexe extension cost?
Our guide range is about £1,960 to £3,720 per m² including VAT. A one-bedroom annexe of about 35 m² is typically £82,000 to £103,000 at standard spec in Nairn.
Does an annexe extension need planning permission?
Usually yes, because of its size and the way it will be used. Councils check that it stays ancillary to the main house, so the application must describe the use clearly.
