Rules in Wales

In Wales, the permitted development allowances for two-storey work cover rear extensions and side extensions set back at least 1 m from the front of the house, so a two-storey front extension needs a householder planning application. The fee is £585 and decisions are normally made within 8 weeks. Building regulations approval under the Welsh Approved Documents follows.

Approval in Wales: Householder planning application: £585. Councils normally decide householder applications within 8 weeks.

Building regulations: Building regulations approval under the Welsh Approved Documents, which differ from England's in places (notably energy efficiency).

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

Getting the design right

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.

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 Dyfed: questions

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

In Wales our guide is £2,020–£2,760 per m² including VAT, so about £24,500–£33,000 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.

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 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 Dyfed?

Dyfed is in Wales. Planning permission is needed for anything built forward of the front wall.
