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.

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.
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 the Isle of Wight: 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.
