Side return extensions in Lanarkshire
Infilling the narrow passage beside a Victorian or Edwardian back addition. Rear extensions in Lanarkshire: we cover 18 towns including East Kilbride, Hamilton and Meikle Earnock, with design, approvals and the build under one contract.

Side returns suit the Victorian and Edwardian terraces found across parts of Lanarkshire, where the kitchen sits in a narrow back addition. Lanarkshire 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.
How much does a side return extension cost in Lanarkshire?
In Lanarkshire, our guide for a side return extension is £2,180–£3,610 per square metre including VAT for a standard specification. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.
| Size | Guide price inc VAT |
|---|---|
| 2 m wide × 6 m deep (12 m²) | £26,000–£43,500 |
| 2.5 m wide × 7 m deep (17.5 m²) | £38,000–£63,000 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission in Lanarkshire?
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.

FAQ
Questions people ask
How much space does a side return add?
Typically 8 to 18 square metres, enough to turn a galley kitchen into a kitchen-diner with an island.
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.
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 you cover all of Lanarkshire?
We cover 18 towns and districts in Lanarkshire, including East Kilbride, Hamilton and Meikle Earnock.
