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, building regulations approval 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.

The main places we list in Cheshire are Warrington (WA1), Chester (CH2), Crewe (CW1), Ellesmere Port (CH65), Widnes (WA8) and Runcorn (WA6). We cover the villages in between too.

Rules in England

In England, a two-storey front extension always needs householder planning permission, because permitted development does not allow any extension forward of the principal elevation. The fee is £548 (or £575 for applications made from 8 December 2026). Councils judge it mainly on design and the street scene, and should decide within 8 weeks of validation.

Approval in England: Householder planning application: £548 (or £575 for applications made from 8 December 2026). Lawful development certificate: £274 (about £288 for applications from 8 December 2026). Councils should decide householder applications within 8 weeks of validation.

Building regulations: Building regulations approval (full plans recommended) from the council or a registered building control approver, with a completion certificate at the end.

The Party Wall etc. Act 1996 applies, so notices may be needed for work on or near a shared wall or boundary.

Getting the design right

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.

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.

Two-storey front extensions in Cheshire: questions

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

In North West England our guide is £2,090–£2,850 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 building regulations approval.

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.

Will I need planning permission in Cheshire?

Cheshire is in England. Planning permission is needed: nothing can go forward of the front wall under permitted development.
