Frequently Asked Questions

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.

Can I appeal a planning refusal?

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

Does my extension need to match existing materials?

While not always mandatory under permitted development, matching materials is often recommended for visual consistency.

How much does a planning application cost?

Fees vary depending on project type and local authority charges.

Will neighbours be notified?

Under prior approval procedures or planning applications, neighbours are typically notified.

Do I need planning permission for a rear extension in Sea Mills?
