What a planning application involves
Getting planning permission for a two-storey extension involves checking whether permitted development applies, preparing drawings and supporting information, submitting a householder application to the council and dealing with questions until a decision is made. Many two-storey extensions need permission, especially side, wraparound and front ones.
Towns in Powys include Newtown (SY16), Brecon (LD3), Welshpool (SY15), Llandrindod Wells (LD1), Knighton (LD7) and Llanidloes (SY17). If yours isn't listed, we still cover it.
Fees
Planning drawings are a guide of £2,000–£3,500, priced in writing before the design stage starts. Householder planning application: £585.
Rules in Wales
In Wales, a householder planning application costs £585, and decisions are normally made within 8 weeks. Wales allows more under permitted development than England, including some two-storey side extensions, so we check the Welsh tests first. Applications go to the local planning authority, and some councils offer pre-application advice.
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
Neighbours' light and privacy
The main concerns on a two-storey extension are usually loss of light, outlook and privacy for neighbours. We test the design against nearby windows and gardens, and adjust depth, roof shape or window positions before submitting.
A complete application
Applications that are missing drawings, the right fee or a certificate of ownership are not validated, and the decision clock does not start. We check the council's validation list so the application is complete on day one.

Planning permission for two-storey extensions in Powys: questions
Should I get pre-application advice from the council?
It can help on sensitive sites, such as conservation areas, corner plots or front extensions, where the council's view is hard to predict. Many councils charge for it and response times vary. For straightforward designs that follow local guidance, a well prepared application is often the quicker route.
