Unfortunately we're not currently able to provide a pre application advice service for householder extensions.
If you'd like guidance on house extensions, we advise you to look at the detailed guidance within our House Extension Guidelines SPG 2 [pdf]. We'd also recommend the Standards for Parking in New Development SPD [pdf] for guidance where there's any change to the size of your house (bedrooms) or where the existing parking provision will be affected by your proposal.
Applications are assessed against the policies set out within our Core Strategy. Links to these documents can be found on our planning policy webpages.
If you're making a pre application enquiry because you're unsure if your proposal requires planning permission then please look at the guidance on the planning portal's interactive house below! Alternatively you can submit an application for certificate of lawful development.
Further information relating to permitted development is available online from the .GOV.UK planning website.
Unfortunately we won't be able to provide a service to meet and discuss alternative proposals if your pre application enquiry relates to an application that's been refused. In this case we'd advise you to look at the officer report which will be available on our website and will explain the reasons for our refusal. We'd also recommend that you refer to the guidance set out in our House Extension Guidelines SPG 2 [pdf].
This will be reviewed later in the year.
