Two-storey rear extension in Annan
For homes in Annan, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.
We cover Annan (DG12) as part of our Dumfries and Galloway work. Two-storey rear extensions suit semi-detached houses in Annan best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Annan?
Whether your two-storey rear extension in Annan needs a planning application depends on its size, your house and any local restrictions.
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. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Annan like to extend?
Post-war semis and terraces are common around Annan, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Two-storey rear extension questions in Annan
Do I need planning permission for a rear extension in Annan?
Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.
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.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
Do you handle building control in Annan?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
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.
