What a planning application involves

This service suits you if you want your two-storey extension to go through planning with the best chance of approval. You get a check of your house's planning history, permitted development rights and local design guidance, a design shaped around them, the application prepared and submitted, and someone to deal with the planning officer's questions. We cannot promise an outcome, but we design to give the application a fair chance.

Across Clwyd we cover Wrexham (LL13), Buckley (CH7), Deeside (CH5), Colwyn Bay (LL28), Flint (CH6) and Rhyl (LL18), plus the smaller places around them.

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.

Design to local guidance

Most councils publish guidance on extensions covering set-backs, roof heights, boundary gaps and neighbours' light. Designing to it from the start makes approval more likely and reduces the chance of being asked to make changes during the application.
