Frequently Asked Questions

Can I extend a semi-detached house differently to a detached house?

Yes, size limits and projection distances differ depending on property type.

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.

Can I extend in a National Park?

National Parks have stricter controls and reduced permitted development rights.

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 build right up to my boundary?

It depends on height and location. Boundary proximity affects allowable eaves height.

How long does a Lawful Development Certificate take?

Most councils determine applications within eight weeks, though timescales may vary.
