Do you need planning permission for a side return extension in Airdrie?
Whether your side return extension in Airdrie needs a planning application depends on its size, your house and any local restrictions.
In Scotland side extensions are more restricted than rear ones under householder permitted development, and wraparounds generally need planning permission. A building warrant is required before work starts.
Scotland has no Party Wall Act. Work to shared walls is governed by property law and the title deeds, so we agree access and protection with neighbours in writing before work begins.
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 Airdrie like to extend?
Airdrie has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Side return extension questions in Airdrie
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
How long does a rear extension take to build in Airdrie?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Glass roof or solid roof with rooflights?
A glass roof gives the most light; a solid roof with long rooflights is warmer and quieter in rain. Both work.
Do I need planning permission for a rear extension in Airdrie?
Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
