What a two-storey front extension involves

A two-storey front extension suits a house with a deep front garden or drive, where the back or side is not practical to extend. You get a design that respects the street, a planning application with drawings that show the extension in context, structural design, a building warrant and the build, carried out by vetted teams working under S&K. At the free site visit we give you a frank view of whether the council is likely to accept 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

Parking and access

Building forward can reduce off-road parking and the space for bins and meters. Councils may weigh up parking, so we check the drive will still work, along with the routes for gas, electricity and water supplies that often enter at the front.

Daylight to existing rooms

A front extension can make the hall and front rooms darker, especially if it covers an existing window. We position new windows to keep the house bright, and check that the new front bedroom gets good daylight without overlooking houses opposite.

Two-storey front extensions in Renfrewshire and Inverclyde: questions

How much does a two-storey front extension cost in Renfrewshire and Inverclyde?

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.

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).

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.

Will the council approve a two-storey front extension?

It depends on the street. Councils are more cautious about front extensions than rear ones because they change the street scene. Approval is more likely where the house is set back, the projection is modest, the design echoes the original house and similar additions already exist nearby. We give you a frank view at the free site visit.

Renfrewshire and Inverclyde 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.
