It is important before you start planning for any building project to be aware of the required documentation needed to obtain a building permit or engage the services of A registered builder. These documents will help you get an accurate idea of what it is you want to achieve, and how much it will cost. Setting a budget at the start of the process is an essential guide for the building designer/architect and your builder so that when you start getting quotes they reflect your expectations. Most documents are directly associated with the proposed project, however in certain cases other documentation may be required to satisfy local council and other specific authorities.
