Frequently Asked Questions

What is the 45-degree rule?

The 45-degree rule is a guideline used by some councils to assess impact on neighbouring properties, particularly in relation to light and outlook.

Can I add a balcony to my extension?

Balconies and raised platforms are not permitted development and usually require planning permission.

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 extend in a National Park?

National Parks have stricter controls and reduced permitted development rights.

How is the original house defined for measurement purposes?

The “original house” refers to the property as it stood on 1 July 1948 or when it was first built, not including later extensions.

What measurements are used for height?

Height is typically measured from the highest ground level adjacent to the building.
