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.

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

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.

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.

Two-storey front extensions in Swansea and Neath Port Talbot: questions

How much does a two-storey front extension cost in Swansea and Neath Port Talbot?

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.

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.

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 Swansea and Neath Port Talbot?

Swansea and Neath Port Talbot is in Wales. Planning permission is needed for anything built forward of the front wall.
