Planning rules that apply in Barry
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.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
Covering Barry
We cover Barry and the postcode districts CF62, CF63. The same team covers Penarth (5 miles), Cardiff (7 miles), Cowbridge (8 miles), all within easy reach.
Just over the Mid Glamorgan border, Caerphilly is about 12 miles away. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
Included in a typical project
- Single-storey extension options assessed first
- Roof designs that tie into the existing hipped or gable roof
- Structural survey before any upward extension
- Level thresholds and accessible layouts
- Planning application where needed
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.

Common questions in Barry
How long does a bungalow extension take to build in Barry?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Barry, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Barry?
Yes. We cover Barry and the surrounding parts of South Glamorgan. Site visits are free and there is no obligation.
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.
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.
