Planning rules that apply in Stonehaven
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. Separately, almost every extension needs a building warrant from the council before work starts.
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.
Applications are decided by your council as planning authority.

Your questions about a single-storey extension in Stonehaven
Do you cover all of Stonehaven?
Yes. We cover Stonehaven and the surrounding parts of Aberdeen and Aberdeenshire. Site visits are free and there is no obligation.
Will my neighbours in Stonehaven 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.
Who do I contract with for a single-storey extension in Stonehaven?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Will I need a steel beam?
Almost always. Opening up the rear wall to join the new room to the house needs a beam, usually steel, sized by a structural engineer. It is included in our quotes.
How much does a single-storey extension cost per square metre?
Our guide range is about £1,720 to £3,330 per m² including VAT, depending on specification. A standard-spec 4 m × 5 m room usually lands at £40,000 to £51,000 in Stonehaven, plus design and council fees.
