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.
We cover postcode districts PA62, PA63, PA64, PA65, PA71 and PA72 in and around Isle of Mull, along with neighbouring Isle of Islay, Oban and Lochgilphead.
What it costs in Isle of Mull
Our guide for Scotland is £2,020–£2,770 per m² including VAT. On a project with an L-shaped footprint of about 28 m² wrapping the side and rear, on two floors (56 m² of new floor space), that puts a two-storey wraparound extension in Isle of Mull at roughly £113,000–£155,500. We'll give you a written design-stage price first, then a fixed build price once the drawings are agreed.

Planning and building standards in Isle of Mull
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 Isle of Mull homes
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.
Phasing the build
A wraparound touches two sides of the house at once, so the kitchen and often the rear rooms are out of use for part of the build. We plan the sequence so you keep a working kitchen and bathroom for as long as possible, or advise when moving out briefly makes sense.

Questions about two-storey wraparound extensions in Isle of Mull
Who handles building standards for a project in Isle of Mull?
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 does a two-storey wraparound extension cost in Isle of Mull?
Our guide for Scotland, which covers Isle of Mull, 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.
Which postcodes do you cover around Isle of Mull?
We cover Isle of Mull (PA62, PA63, PA64, PA65, PA71 and PA72) and nearby places including Isle of Islay, Oban and Lochgilphead, plus the rest of Argyll and Bute. Visits and projects in Isle of Mull are by arrangement, with travel costs agreed in writing first.
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.
Does a wraparound extension need steel?
Almost always. Opening the corner of the house and the old rear wall to make one open-plan space means steel beams, and often a steel post or frame at the outside corner. The structural engineer sizes these, and the steel is ordered once the design is fixed, which is one reason a wraparound needs careful sequencing.
