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.

Across Bedfordshire we cover Luton (LU1), Bedford (MK40), Dunstable (LU5), Leighton Buzzard (LU7), Ampthill (MK45) and Kempston Hardwick (MK42), plus the smaller places around them.

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

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.

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 Bedfordshire: questions

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

In the East of England our guide is £2,270–£3,090 per m² including VAT, so about £27,000–£37,000 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.

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.

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 building regulations approval.

Will I need planning permission in Bedfordshire?

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