Frequently Asked Questions

Can I build an outbuilding in my garden?

Outbuildings may be permitted development if they meet height, location, and usage restrictions.

Is planning permission needed for internal alterations?

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

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.

Do permitted development rights expire?

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

Are side extensions allowed under permitted development?

Side extensions are permitted in some cases, but must not exceed half the width of the original house and must meet height limits.

Can I build right up to my boundary?

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