9. After the planning decision
If the application is refused the applicant can appeal to the planning inspectorate.
If the application is approved, there will usually be conditions that need to be discharged. There is an application form and a fee payable for each request (not per condition). You can apply online or download a paper form from the applying for planning permission page.
If you want to amend your planning permission you can apply to make very minor changes as a Non Material Minor Amendment. Changes that are still minor in nature but may have more impact will require a Variation of Condition application to change the plans condition. More substantial changes may require a new planning permission. You can apply online or download a paper form from the applying for planning permission page.
You should contact Devon Building Control to discuss whether building regulations is required.
