The three stages of a knock down rebuild


The knock down rebuild of your existing home offers many benefits including enabling your family to continue to live in your existing community while replacing your existing house with one that better suits your needs.

At ANSA Homes we’ve guided many delighted customers through the knock down rebuild process, part of which involves highlighting the fact that a successful knock down rebuild requires research and preparation.
We break the knock down rebuild process into three distinct phases:

  1. Investigation and research;
  2. Choosing your builder and home design; and
  3. Building your new home.

Stage 1: Investigating and researching your knock down rebuild project

The foundation of any successful knock down rebuild project is research. You need to investigate whether you’re permitted to knock down your existing house and gather information about what you are permitted to build in its place.

The first thing you should do is obtain a Section 10.7 Planning Certificate (formerly known as a Section 149 certificate) from the relevant local council. This certificate will provide you with information such as zoning and whether Draft Local Environmental Plans and Development Control Plans affect the land. It will also be able to tell you whether any restrictions apply to the land due to things like flooding and bushfires. Restrictions of this latter type can be reviewed by councils after natural disasters like our bushfires so it is important to always check.

Some homes may also be subject to Heritage Overlays which are part of local council planning schemes. They include places of local and state significance. You should be aware that front facades of homes that have heritage overlays are the most difficult to change. A council is more likely to allow the back of a property to be knocked down or rebuilt rather than the front. This is because often a heritage building is part of a local heritage area and streetscape needs to be maintained.

Vegetation like certain types of trees may also be protected and not be able to be removed so these need to be considered in any plans you make.
A further option once a design is determined is to take the route of Complying Development. This is a combined planning and construction approval for building that can be determined through a fast track assessment. However, while it is quicker than going through council, it is often more stringent. It should also be noted that this process will still take into account council regulations and the relevant State Environmental Planning Policies (SEPPs).

If you aren’t familiar with different planning certificates and policies, the information can seem overwhelming. ANSA Homes are happy to guide you through this process and in particular go through the documents with you free of charge so that you are able to make informed decisions.

Choosing your builder and home design

Once you’ve established that you can demolish your existing house, you then enter the fun part of your knock down rebuild project. You are now free to browse the market, visit display homes and consult with builders on designs that appeal to you. As a HIA and MBA award-winning Sydney builder with a proven track record in successfully delivering knock down rebuild projects, our various display homes across Western Sydney (Marsden Park, Oran Park, and Edmondson Park) are a great place to start.
Then there are decisions you need to make based on your current and future needs like the number of bedrooms, bathrooms and living areas. Do you want a double-storey or single-storey home? How about including a granny-flat to accommodate your extended family or adult children, or to rent out for an additional income stream?

This part of the knock down rebuild process can seem daunting which is why it’s important to find a builder with previous success in knock down rebuild – a builder who understands your needs and can give you the right advice. ANSA Homes offer a free knock down rebuild consultation to help you avoid the common pitfalls and our team can help you determine what site inspections and reports may be required.

Obviously, budget is a key part of any conversation with a potential builder and once again you need to undertake your own research. Unlike many builders, ANSA Homes provides certainty of price upfront as part of the ANSA Certainty Promise. The ANSA team ensures that you are kept informed throughout the tender process, so you have peace of mind and certainty of the end price. With ANSA Homes, you’ll never get any nasty surprises that push costs beyond your budget.

Demolishing your existing home

With most builders, the demolition is the responsibility of the homeowner, but ANSA Homes can help you manage the process by recommending a demolition specialist with a proven track record of getting the job done efficiently and affordably. We can assist with getting the relevant approvals in place before demolition takes place, while you contact your utility providers to have your gas and power disconnected.

Stage 3: Let the fun begin: building your new home

Arguably the most exciting phase is the actual building of your new dream home. At ANSA Homes we arrange regular site inspections that will make you feel part of the whole knock down rebuild process. We deliberately limit the number of homes we build each year so we can provide customers with the best service we can.

To provide you with certainty and understanding of the knock down rebuild process, the ANSA Homes team has developed a detailed knock down rebuild guide based on the most critical topics and our most frequently asked questions.
