With choosing to knock down rebuild, the knock down rebuild cost Sydney will depend on your unique block and chosen home design and upgrades, however, there are many reasons why knock down rebuild is the more affordable option.

Upfront pricing
Your chosen builder will be able to provide you a quote to knock down and rebuild based on the chosen design and block of land after a site inspection. You can also receive a quote from a demolition supplier for the cost to knock down your home. Builders have more economies of scale, meaning you can benefit from existing relationships with suppliers, providing more bulk ordering of materials - lower costs.

Unwanted costs
Choosing to renovate may seem like it's more affordable to renovate your home however, substantial renovations can actually cost more than a knock down rebuild. 

As you are renovating an existing dwelling, this requires dismantling sections of a house without disturbing the wiring, plumbing or structural integrity. You are also working with materials that may no longer be in use or damaged. Examples include; lack of proper waterproofing which can damage the timber framing, outdated wiring which may be unsafe, structural damage due to age, water damage or infestation, and potential foundation subsidence. All of these issues may cause more unforeseen costs.

Starting from scratch to knock down and rebuild your home ensures your home is BASIC certified, meaning it is energy efficient, uses safer, long-lasting materials as per the latest building standards. Your new home is built to last.
