Do you need planning permission for a single-storey rear extension in Stornoway?
Here is how the rules in Scotland apply to a single-storey rear extension in Stornoway.
In Scotland a single-storey rear extension can be permitted development under Class 1A: eaves no higher than 3 metres and an overall height of 4 metres, and where any part is within 1 metre of a boundary it can project no more than 3 metres on a terraced house or 4 metres on other houses. The rights do not apply in conservation areas, and a building warrant is still needed before work starts.
Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.
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 Stornoway like to extend?
Traditional stone houses sit alongside modern bungalows and timber-frame homes around Stornoway. A lighter, contrasting addition at the back often suits older stone houses better than trying to copy the walling.

FAQ
Single-storey rear extension questions in Stornoway
Is the site visit in Stornoway free?
Visits here are by arrangement; we confirm whether we can take the job and agree any travel costs first.
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 the extension make the room behind it dark?
Not if it is designed well. Rooflights or a lantern over the old back room, and a wide opening into it, keep daylight reaching the middle of the house.
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.
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 you handle building control in Stornoway?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
