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 Oban (PA34, PA35 and PA37) and the places around it, including Lochgilphead (26.1 miles), Fort William (30.9 miles) and Caol.

Planning and building standards in Oban
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 Oban 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.
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.
How we'd run your project
Visit by arrangement
We agree a visit to your home in Oban and any travel costs with you in writing first, then look at the structure, access and boundaries.
Choose the approval route
Some designs fit permitted development, most need a householder application. We decide which applies in Scotland before drawing in detail.
Price it properly
Once the engineer's calculations are in, we fix the build price in writing, with a clear list of what's included.
Build
Foundations, walls, floor, roof, windows, then first and second fix. We break through into the house as late as we can.
Questions about two-storey wraparound extensions in Oban
How much does a two-storey wraparound extension cost in Oban?
Our guide for Scotland, which covers Oban, 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.
How long does a two-storey wraparound extension take?
Allow 4 to 8 weeks for survey and design, then the approval period (councils have two months to decide a local planning application), then 4 to 8 weeks of technical design, which can overlap. The build itself usually takes 14 to 20 weeks, longer for large or complex designs.
Who handles building standards for a project in Oban?
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.
Can a wraparound extension be part single, part two-storey?
Yes. Many wraparounds keep the rear part single storey with roof lights over the kitchen and put the two-storey part to the side. This can reduce the effect on neighbours and the cost. We set out both options at the design stage, so you can compare floor space against price before choosing.
