Will the council need to approve it?
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.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
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.
When a utility room extension makes sense

Your questions about a utility room extension in Helensburgh

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.
Do you cover all of Helensburgh?
Yes. We cover Helensburgh and the surrounding parts of Argyll and Bute. Site visits are free and there is no obligation.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Helensburgh, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Does a utility extension need planning permission?
Often not, if it is single storey and within permitted development limits. We check this for your property.

Our guide range is about £1,860 to £3,430 per m² including VAT, with a minimum of around £14,000. An 8 m² standard-spec utility is typically £17,500 to £22,000 in Helensburgh.
