Planning and approvals in Annan
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Applications are decided by your council as planning authority.

Bungalow extension questions answered
Do I need building regulations approval in Annan?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Do you cover all of Annan?
Yes. We cover Annan and the surrounding parts of Dumfries and Galloway. Site visits are free and there is no obligation.
Will my neighbours in Annan be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,720 to £3,330 per m² including VAT. Going upwards is priced after a structural survey.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
