About a two-storey wraparound extension

A two-storey wraparound extension is an L-shaped addition that extends both the side and the rear of your house, on two floors. It gives one of the largest gains in floor space of any extension, typically a big open-plan kitchen and living area below and two or more bedrooms or bathrooms above.

Around Innerleithen we also work in Peebles, Galashiels and Selkirk, and across the rest of the Scottish Borders. Postcode districts in and near Innerleithen: EH43 and EH44.

What it costs in Innerleithen

Guide prices for two-storey wraparound extensions in Scotland are around £2,020–£2,770 per m² of new floor space, including VAT. For 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), that's roughly £113,000–£155,500. Steelwork for wide openings is the item most likely to move the figure; we'll know once the engineer has designed it.

Planning and building standards in Innerleithen

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 Innerleithen 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.

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 Innerleithen

Which postcodes do you cover around Innerleithen?

We cover Innerleithen (EH43 and EH44) and nearby places including Peebles, Galashiels and Selkirk, plus the rest of the Scottish Borders. The first site visit is free.

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.

Do I need planning permission for a two-storey wraparound extension in Innerleithen?

Innerleithen 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.

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.
