About a two-storey wraparound extension
A two-storey wraparound extension suits a house with space both beside it and behind it, where you want to transform the layout rather than add a single room. You get one design for the whole L-shape, the planning application, structural design for the corner and the openings into the house, a building warrant and the build, managed by us and carried out by vetted teams working under S&K.
Around Rothesay we also work in Largs, Dunoon and Gourock, and across the rest of Argyll and Bute. Postcode districts in and near Rothesay: PA20 and PA21.

Planning and building standards in Rothesay
In Scotland, a two-storey wraparound would need to be at least 10 m from every boundary to be permitted development under Class 1B, and not on an elevation fronting a road. That is rarely possible, so plan for a householder planning application, which costs £371 and is decided within two months, followed by a building warrant before work starts.
Approval in Scotland: Householder planning application: £371. Councils have two months to decide a local planning application.
Building standards: 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.
Design points for Rothesay homes
The corner post
At the outside corner of the L, there is no existing wall to carry the floor above. Opening the ground floor fully usually means a steel frame or a corner post, and the engineer's design sets how slim it can be. We decide early whether you want a clear corner or a visible post.
Two roofs that meet
A wraparound needs the side roof and rear roof to join cleanly, often with a valley or hip where they meet. Getting pitches and ridge heights right keeps rainwater moving and avoids a bulky mass at the back corner, which neighbours and planners notice.

Questions about two-storey wraparound extensions in Rothesay
How much does a two-storey wraparound extension cost in Rothesay?
Our guide for Scotland, which covers Rothesay, is £2,020–£2,770 per m² including VAT. A typical project with an L-shaped footprint of about 28 m² wrapping the side and rear, on two floors (56 m² of new floor space) comes to about £113,000–£155,500. Design and approval fees are extra, and we fix the build price in writing once the design is agreed.
Do I need planning permission for a two-storey wraparound extension in Rothesay?
Rothesay 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.
Who handles building standards for a project in Rothesay?
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.
How much floor space does a wraparound extension add?
It depends on the width of the side plot and the depth at the rear. Our guide prices are based on a typical wraparound with an L-shaped footprint of about 28 m² wrapping the side and rear, on two floors (56 m² of new floor space). Yours may be larger or smaller, and the measured survey shows what your plot can take.
Is a wraparound extension better than separate side and rear extensions?
Building both at once usually costs less than two separate projects, because you pay for one set-up, one scaffold, one roof junction and one set of approvals. It also lets the layout be designed as a whole. The trade-off is a larger single outlay and a longer build, often 16 to 24 weeks at this size.
