Frequently Asked Questions

Will neighbours be notified?

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

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 build an outbuilding in my garden?

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

What is the maximum size allowed under permitted development?

Size limits depend on property type and location. Detached houses may have larger rear extensions than terraced homes, subject to height and boundary constraints.

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 remove a chimney without permission?

External alterations may require permission depending on property type and location.
