Frequently Asked Questions

What is the maximum rear projection allowed?

Detached houses may extend up to four metres under standard rules, or eight metres with prior approval. Smaller limits apply to other house types.

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.

Will neighbours be notified?

Under prior approval procedures or planning applications, neighbours are typically notified.

Is there a limit on total site coverage?

Yes. Extensions and outbuildings combined must not cover more than 50% of the curtilage of the original house.

Can I extend onto agricultural land?

Residential permitted development rights apply only within the residential curtilage.

How much does a planning application cost?

Fees vary depending on project type and local authority charges.
