Frequently Asked Questions

Can I extend above a single-storey extension?

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

Can I build right up to my boundary?

It depends on height and location. Boundary proximity affects allowable eaves height.

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.

What measurements are used for height?

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

Are there restrictions on side-facing windows?

Yes. Upper-floor side-facing windows typically must be obscure-glazed and non-opening below a certain height.

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.
