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

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.

Do I need prior approval for a larger extension?

In some cases, larger home extensions require a prior approval process where neighbours are notified and the council assesses certain impacts.

Can I build over a sewer?

Building near or over a public sewer may require a build-over agreement from the relevant water authority.
