Planning and approvals in Argyll and Bute
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.
The planning position for a specific Argyll and Bute address depends on its history and any designations, which is why we check it at the first visit.
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.
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.

Our process, step by step
Free site visits on the mainland; island and remote addresses by arrangement, with travel costs agreed first.
Site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
You receive a written, itemised price and programme. Nothing starts until you are happy with it.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Questions people ask about pitched roof extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Argyll and Bute, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Argyll and Bute?
Yes, across the whole of Argyll and Bute. Free site visits on the mainland; island and remote addresses by arrangement, with travel costs agreed first.
Do I need building regulations approval in Argyll and Bute?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Is a pitched roof better than a flat roof?
Neither is better in all cases. Pitched roofs blend with traditional houses and shed water quickly; flat roofs give more headroom and suit modern designs and lanterns.
How much does a pitched roof extension cost?
Our guide range is about £1,810 to £3,430 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
