Do you need planning permission for a two-storey rear extension in Milngavie?
Here is how the rules in Scotland apply to a two-storey rear extension in Milngavie.
In Scotland an extension of more than one storey is only permitted development (Class 1B) if no part is within 10 metres of any boundary and it is no higher than the existing house, so almost every two-storey rear extension needs planning permission and a building warrant.
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 Milngavie like to extend?
Post-war semis and terraces are common around Milngavie, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Two-storey rear extension questions in Milngavie
Can you match the brick or stone on my Milngavie house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How long does a rear extension take to build in Milngavie?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Does a two-storey rear extension need planning permission?
Almost always. England and Northern Ireland allow 3 metres without an application only if at least 7 metres remains to the rear boundary; Wales and Scotland are similar or stricter.
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.

Including G61 and G62, and the surrounding Glasgow and the Clyde 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.
