Is a bungalow extension right for your house?
- Families wanting more space on one floor
- Homeowners planning for later life
- Bungalows on larger plots
Bungalow roofs are often hipped, which makes tying in an extension roof a careful job. We draw the roof junction early because it drives both the look and the cost.
Will the council need to approve it?
In Wales single-storey bungalow extensions follow the normal limits (up to 4 m at the rear); adding a storey needs planning permission.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.

How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,630 to £3,160 per m² including VAT. Going upwards is priced after a structural survey.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
