Frequently Asked Questions

Can I extend above a single-storey extension?

Possibly, but this often requires planning permission and must comply with height and design considerations.

Is planning permission needed for internal alterations?

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

Can I extend a house that has already been extended?

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

Do permitted development rights expire?

Permitted development rights generally remain unless removed by condition or Article 4 Direction.

Does building regulations approval still apply?

Yes. Even if planning permission is not required, building regulations approval is usually still necessary.

Can I submit planning drawings myself?

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