What a two-storey front extension involves

A two-storey front extension is an addition built forward of the front wall of your house on both floors, often a deeper hall or study below and a larger bedroom above. It suits houses set well back from the road.

Towns in Ayrshire include Kilmarnock (KA1), Ayr (KA6), Irvine (KA11), Kilwinning (KA13), Troon (KA10) and Prestwick (KA8). If yours isn't listed, we still cover it.

Guide price in Scotland

Expect a two-storey front extension in Ayrshire to land somewhere around £25,000–£34,000 for a 3 m × 2 m footprint on two floors (12 m² of new floor space). Our Scotland guide rate is £2,070–£2,820 per m², including VAT. Steelwork for wide openings is the item most likely to move the figure; we'll know once the engineer has designed it.

Rules in Scotland

In Scotland, Class 1B permitted development does not cover an extension on an elevation fronting a road and requires 10 m to every boundary, so a two-storey front extension needs a householder planning application. The fee is £371 and councils have two months to decide. A building warrant is then needed 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.

There is no Party Wall Act in Scotland. Shared walls and boundaries are governed by title deeds and common law, so we speak to neighbours early and record the condition of shared structures.

Getting the design right

Respecting the building line

Councils pay close attention to how far a front extension projects past the line of neighbouring houses. A shallow projection, often a gable or bay that echoes the original design, has a much better chance of approval than a deep box. We look at the street before drawing anything.

Roof and gable design

A front extension is the most visible part of the house, so the roof needs to look deliberate: a matching gable, a hipped bay or a porch roof below a first-floor bay. We match the pitch and materials and keep the ridge below the main roof.

Two-storey front extensions in Ayrshire: questions

How much does a two-storey front extension cost in Ayrshire?

In Scotland our guide is £2,070–£2,820 per m² including VAT, so about £25,000–£34,000 for a 3 m × 2 m footprint on two floors (12 m² of new floor space). Essential and Premium specs move that by roughly 8% down or 20% up.

Does a front extension affect my parking?

It can. If it is built over part of the drive you may lose a parking space, and some councils consider whether enough off-road parking remains. We measure the drive at the survey and show on the drawings how cars, bins and meters will fit after the work.

Can I combine a front extension with a porch?

Yes. A common approach is a two-storey bay or gable with a single-storey porch roof running across the front door. This gives a bigger hall and front bedroom while breaking up the mass of the front wall. Both parts are covered by the same planning application and a building warrant.

How far forward can a front extension go?

There is no fixed figure, because a two-storey front extension needs planning permission and the council decides case by case. Many councils' design guides favour a shallow projection that keeps a clear front garden. Our guide prices assume a modest example with a 3 m × 2 m footprint on two floors (12 m² of new floor space).

Will I need planning permission in Ayrshire?

Ayrshire 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.
