Do you need planning permission for a side return extension in Motherwell?
Whether your side return extension in Motherwell 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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Motherwell like to extend?
Post-war semis and terraces are common around Motherwell, and many have room for a single-storey rear extension within Class 1A limits.

We measure the house and garden, look at the back wall, drainage and boundaries, and talk through what you want from the space.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Planning and regulations

FAQ
Side return extension questions in Motherwell
Is the site visit in Motherwell free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do I need planning permission for a rear extension in Motherwell?
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.
Where does the drainage go?
Side passages often carry the soil and rainwater pipes. We survey them first and reroute them under the new floor where needed.
Can you match the brick or stone on my Motherwell house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
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.
