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.

Suffolk towns we list: Ipswich (IP1), Lowestoft (NR32), Bury St Edmunds (IP29), Haverhill (CB9), Felixstowe (IP11) and Sudbury (Suffolk) (CO10). Every other address in Suffolk is covered as well.

Guide price in the East of England

Guide prices for two-storey front extensions in the East of England are around £2,270–£3,090 per m² of new floor space, including VAT. For a typical project with a 3 m × 2 m footprint on two floors (12 m² of new floor space), that's roughly £27,000–£37,000. Steelwork for wide openings is the item most likely to move the figure; we'll know once the engineer has designed it.

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

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.

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.

Two-storey front extensions in Suffolk: questions

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

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.

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.

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 Suffolk?

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