Do I need planning permission in Pembroke Dock?
In Wales single-storey bungalow extensions follow the normal limits (up to 4 m at the rear); adding a storey needs planning permission.
The planning position for a specific Pembroke Dock address depends on its history and any designations, which is why we check it at the first visit.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

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.

Questions people ask about bungalow extensions
Do you cover all of Pembroke Dock?
Yes. We cover Pembroke Dock and the surrounding parts of Dyfed. Site visits are free and there is no obligation.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Pembroke Dock, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How long does a bungalow extension take to build in Pembroke Dock?
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.
