Do I need planning permission in Aberystwyth?
In Wales single-storey bungalow extensions follow the normal limits (up to 4 m at the rear); adding a storey needs planning permission.
In a conservation area, national park, National Landscape or World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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).

Build and sign-off

Your questions about a bungalow extension in Aberystwyth
How long does a bungalow extension take to build in Aberystwyth?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
Do you cover all of Aberystwyth?
Yes. We cover Aberystwyth and the surrounding parts of Dyfed. Site visits are free and there is no obligation.
Do I need building regulations approval in Aberystwyth?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
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.
