Provided the renovation is not a major structural change, you usually do not need council approval such as Building Consent. Some outdoor areas (decks and pergolas etc.) may require council approval if they are changing the structure of your house, or impacting your neighbours. When discussing your proposed renovations, Japan Homes can advise you whether you need to get Building Consent from local Council. Typically, if you need to go through council approval, our LBP-registered designer will be able to assist with the application.
