Planning and building control in Inverness
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.
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.
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.
What works best for Inverness houses?
Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Start by comparing bungalow extensions, single-storey rear extensions and orangery extensions: between them they cover most of the layouts we see requested for houses like these.

Questions about extensions in Inverness
How much does an extension cost in Inverness?
Using our Scotland factor (×0.98), a standard-spec single-storey extension of 20 m² is a guide £40,000 to £51,000 including VAT, and a 32 m² two-storey extension £56,000 to £74,000. Your written price follows the survey.
Do you cover all of Inverness?
Yes, including the surrounding parts of Highlands and Islands. Site visits are free and there is no obligation.
Will my neighbours need to be told?
If you apply for planning permission the council notifies neighbours, and we agree access with them in writing for work near a shared boundary.
Do I need planning permission for an extension in Inverness?
Not always. It depends on the size, position and your property's history. Scottish householder rules allow some smaller extensions without an application, but a building warrant is still needed.
Do you handle building regulations?
Yes. We prepare the drawings and calculations, submit them and book inspections, and in Scotland we apply for the building warrant before work starts.
