A knockdown rebuild is knocking down the original structure on the property to be able to build something new in its place. Knocking down means there are no remains of the original structure; it’s essentially starting from scratch. Rebuilding means there is an entirely new home in its place.
The process of knocking down a house requires a demolition crew to remove all the structures of the original house and prepare the land for the new structure. The next stage will require an architect or a draftsperson to guide you through the house’s design process to meet your expectations, or a standard plan can be chosen. Once the demolition is complete, you’ll need to contract builders to build the new house; this is where the excitement happens. The building process can be long and doesn’t always go to plan.
The process can commence once you have received council approval. You will need council approval for a knockdown rebuild or permission from neighbours who may have a covenant on your block regarding development. Once you have received permission, you will need to find a demolition company that will also need to see a demolition permit. After they have approved, you will need to disconnect electricity and gas through your utility company. Following local community guidelines, the demolition company will also have to cap off the sewer at the main sewer connection point. After the demolition is complete and the land is clear for you to rebuild, you can begin the fun!
The process of knocking down and rebuilding can take anywhere between roughly eight to twelve months. There can be numerous delays caused by the weather and site issues.
The cost to knockdown and rebuild is split into three major costs: the demolition cost, the rebuild, and the administration costs.
Demolition will cost about $20,000 to $40,000; this depends on the size of the block and any issues that may arise whilst in the demolition process.
The renovation cost can vary depending on the size, amount of rooms and all the different materials of the house that you choose. The larger the space and the higher quality of materials you choose will increase the price. Renovating can range from $500,000 on average up to $6-700,000 for a comfortable three-bedroom home.
