Do you need planning permission for a side return extension in Selkirk?
Here is how the rules in Scotland apply to a side return extension in Selkirk.
Scottish householder rights treat the side part of a wraparound or side infill more strictly than a plain rear extension, so most need planning permission, and all need a building warrant.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
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 Selkirk like to extend?
Selkirk 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 Selkirk
Do you handle building control in Selkirk?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
Is a side return permitted development?
Sometimes, as a side extension within the width and height limits, but not in conservation areas, and many terraces are in one.
How long does a rear extension take to build in Selkirk?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
Can you match the brick or stone on my Selkirk house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
