Frequently Asked Questions

Can I appeal a planning refusal?

Yes. Applicants may appeal to the Planning Inspectorate within specified time limits.

How close can I build to my neighbour’s boundary?

Extensions built close to a boundary must meet height and eaves restrictions, especially if within two metres of the boundary.

Is planning permission needed for internal alterations?

Internal changes usually do not require planning permission unless the property is listed.

How is the original house defined for measurement purposes?

The “original house” refers to the property as it stood on 1 July 1948 or when it was first built, not including later extensions.

Can I build over a sewer?

Building near or over a public sewer may require a build-over agreement from the relevant water authority.

Do I need prior approval for a larger extension?

In some cases, larger home extensions require a prior approval process where neighbours are notified and the council assesses certain impacts.
