Do you need planning permission for a single-storey rear extension in Armadale?
Here is how the rules in Scotland apply to a single-storey rear extension in Armadale.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Armadale like to extend?
Post-war semis and terraces are common around Armadale, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Single-storey rear extension questions in Armadale
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.
Can you match the brick or stone on my Armadale house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
What postcode areas do you cover around Armadale?
Including EH47 and EH48, and the surrounding Edinburgh and the Lothians area.
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.
Do you handle building control in Armadale?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
