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. Because it changes how the house looks from the street, it always needs planning permission in England and is judged closely on design. It suits houses set well back from the road.

Towns in Derbyshire include Derby (DE1), Chesterfield (S40), Long Eaton (DE72), Ilkeston (DE7), Swadlincote (DE11) and Staveley (S43). If yours isn't listed, we still cover 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.

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 Derbyshire: questions

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

In the East Midlands our guide is £2,160–£2,940 per m² including VAT, so about £26,000–£35,500 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.

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.

Will I need planning permission in Derbyshire?

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