About a two-storey extension for a detached house
A two-storey extension for a detached house is a two-floor addition to the side, rear or both of a house that stands on its own plot. Detached houses often have room on more than one side, so there is more choice of layout and fewer shared-wall issues. The design still needs to respect boundaries, neighbours' windows and the look of the house.
Around Campbeltown we also work in Girvan, Ardrossan and Saltcoats, and across the rest of Argyll and Bute. Postcode district in and near Campbeltown: PA28.

Design points for Campbeltown homes
Choosing the best side
On a detached house you can often extend on either side or the rear. We look at orientation for daylight, where the stairs and landing are, the distance to each boundary, drains and trees, so the extension goes where it adds the most useful space.
Keeping it subordinate
Large detached houses can take a large extension, but councils still expect it to look secondary to the main house. A lower ridge, a modest set-back at the front and matching materials keep the proportions right, even on a wide plot.
How we'd run your project
Visit by arrangement
We agree a visit to your home in Campbeltown and any travel costs with you in writing first, then look at the structure, access and boundaries.
Get it approved
Once you're happy with the design we submit it to the council for Campbeltown and deal with any questions from the planning officer.
Structure and building standards
A structural engineer sizes the foundations and steels, and we get a building warrant before work starts.
Build and sign-off
Vetted teams working under S&K build the extension, and we arrange the completion certificate at the end.

How much does a two-storey extension for a detached house cost in Campbeltown?

Who handles building standards for a project in Campbeltown?
We handle it as part of the project. What's needed in Scotland: a building warrant from the council's building standards service before work starts, and a completion certificate at the end. Scotland uses its own Technical Handbooks. We prepare the drawings and the engineer's calculations, book the inspections and pass you the completion paperwork at the end.
Do I need planning permission for a two-storey extension for a detached house in Campbeltown?
Campbeltown is in Scotland. Planning permission is usually needed: Class 1B permitted development only applies if every part of the extension is at least 10 m from all boundaries. A building warrant is needed before work starts.
Can I extend a detached house on both sides?
Sometimes. With planning permission, a council may accept extensions on both sides if the house stays well proportioned and keeps gaps to the boundaries. It is more common to extend on one side and the rear, or with a wraparound. We look at the plot as a whole before suggesting more than one extension.
Is a detached house extension a better investment than moving?
It often costs less than the gap between your house and a larger one nearby, once property tax, legal fees and removal costs are counted, but that depends on your area. Extending also has limits: every street has a ceiling price. We give you build costs so you can compare them with local asking prices.
