Frequently Asked Questions

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 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.

How high can my extension be?

Height limits vary, but rear extensions under permitted development generally cannot exceed four metres for detached houses or three metres for others.

Can I build an outbuilding in my garden?

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

Does permitted development apply to HMOs?

Some permitted development rights may be restricted depending on property use class.

Can I extend above a single-storey extension?

Possibly, but this often requires planning permission and must comply with height and design considerations.
