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 North Yorkshire include York (YO1), Middlesbrough (TS1), Harrogate (HG1), Scarborough (YO11), Redcar (TS10) and Selby (YO8). If yours isn't listed, we still cover it.

Getting the design right

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.

Check the history first

Planning conditions from when the house was built, earlier extensions and Article 4 directions can all remove permitted development rights. We check the council's records and your house's history before design starts, so the route is clear.

Planning permission for two-storey extensions in North Yorkshire: 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.

What happens if my planning application is refused?

You can change the design and apply again, or appeal. In England, a householder appeal must usually be made within 12 weeks of the decision. Often the best route is a revised design that answers the reasons for refusal. We read the officer's report and advise which option has the better chance.
