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 Denny (FK4 and FK6) and the places around it, including Larbert (3.1 miles), Stenhousemuir (3.6 miles) and Bannockburn.

What it costs in Denny

In Scotland, which includes Denny, we'd expect a two-storey wraparound extension to cost around £113,000–£155,500 for an L-shaped footprint of about 28 m² wrapping the side and rear, on two floors (56 m² of new floor space), or £2,020–£2,770 per m² including VAT. The fastest way to a firmer number is a free site visit, after which we price the design stage in writing.

Planning and building standards in Denny

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 Denny homes

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.

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.

Can I stay at home during a wraparound extension?

Many people do, but a wraparound affects two sides of the house and usually the kitchen, so there will be weeks without a full kitchen. We plan a temporary kitchen, keep a route through the house and seal off the work area. For some families, moving out while the rear wall is opened up is easier.

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.
