Frequently Asked Questions

Will permitted development rules change?

Planning legislation can change over time, so it is important to check current regulations.

Are garden rooms permitted development?

Garden rooms may qualify if they meet size and usage limits and are not used as separate accommodation.

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.

Can I build an outbuilding in my garden?

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

Does my extension need to match existing materials?

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