Do you need planning permission for a single-storey rear extension in Inverness?
Here is how the rules in Scotland apply to a single-storey rear extension in Inverness.
Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.
Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Inverness like to extend?
Inverness has sandstone tenements, terraced houses and villas closer in, with post-war semis and newer estates further out. Tenement and other flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Single-storey rear extension questions in Inverness
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Is the site visit in Inverness free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Is a flat roof or a pitched roof better?
A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.
Can you match the brick or stone on my Inverness house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How long does a rear extension take to build in Inverness?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
What postcode areas do you cover around Inverness?
Including IV1 and IV3, and the surrounding Highlands and Islands area.
