Kelso is covered from our Scottish Borders round, including TD5. In Kelso we check the boundary line and the neighbour's gutter before drawing a side return, because a few centimetres decide whether the wall goes on or beside the boundary.

Do you need planning permission for a side return extension in Kelso?
The planning route for a side return extension in Kelso is set by Scotland's householder rules and your council.
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 Kelso like to extend?
Kelso 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 Kelso
Is the site visit in Kelso free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Kelso?
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 combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
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.
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.
Do I need planning permission for a rear extension in Kelso?
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.
