Do you need planning permission for a single-storey rear extension in Brechin?
Here is how the rules in Scotland apply to a single-storey rear extension in Brechin.
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.
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 Brechin like to extend?
Post-war semis and terraces are common around Brechin, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Single-storey rear extension questions in Brechin
Is the site visit in Brechin free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Brechin?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is a flat roof or a pitched roof better?
A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.
Do you handle building control in Brechin?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
