Do you need planning permission for a side return extension in Fort William?
The planning route for a side return extension in Fort William is set by Scotland's householder rules and your council.
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 Fort William like to extend?
Traditional stone houses sit alongside modern bungalows and timber-frame homes around Fort William. A lighter, contrasting addition at the back often suits older stone houses better than trying to copy the walling.

FAQ
Side return extension questions in Fort William
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
Can you match the brick or stone on my Fort William house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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 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 I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
