Do you need planning permission for a semi-detached rear extension in Blairgowrie and Rattray?
Planning for a semi-detached rear extension in Blairgowrie and Rattray follows the Scottish householder rules.
Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
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 Blairgowrie and Rattray like to extend?
Post-war semis and terraces are common around Blairgowrie and Rattray, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Semi-detached rear extension questions in Blairgowrie and Rattray
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.
Can you match the brick or stone on my Blairgowrie and Rattray house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
What if my neighbour has already extended?
That can make a matching depth easier to justify. We measure theirs at the survey.
Do you handle building control in Blairgowrie and Rattray?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
How much does a semi-detached rear extension cost in Blairgowrie and Rattray?
