Frequently Asked Questions

Can I extend my house in a flood zone?

Extensions in flood risk areas may require additional assessments and possibly planning permission.

Can I extend a house that has already been extended?

Permitted development limits are cumulative, so previous extensions may reduce what is still allowed.

Can I build a two-storey extension without planning permission?

Two-storey extensions are sometimes permitted, but stricter limits apply to height, rear projection distance, and window placement to avoid overlooking neighbours.

Can I submit planning drawings myself?

Yes, but professional plans improve clarity and reduce refusal risk.

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.

How high can my extension be?

Height limits vary, but rear extensions under permitted development generally cannot exceed four metres for detached houses or three metres for others.
