This knock down rebuild price guide gives you an overall insight. Let’s dive deeper to know more. 

What is a Knockdown Rebuild?

Knockdown rebuild involves the demolition of your current home and the construction of a completely new one on the same piece of land. Rather than relocating to a different suburb or renovating your home extensively, you start fresh while keeping your location.

This is a common practice in established suburbs where the land is valuable, but the homes are old and in need of upgrades. It gives you the chance to build a home that meets your lifestyle requirements without having to worry about the problems that come with renovations.

The procedure involves the demolition of the site, land clearing, design planning, council approval, and full construction. While it may sound complex, many home builders offer complete packages that manage each stage for you.

Now that you understand the basics, let’s look at the actual costs involved.

Key Factors Influencing the Knockdown Rebuild Cost

Several factors affect the cost to knock down and rebuild. Let’s look at knockdown rebuild cost factors in detail. 

➢ Location of Your Property

The cost to knock down and rebuild can be significantly affected by location. The cost of labor is higher in big cities like Sydney and Melbourne than in rural areas. Block access can further add to the cost. If your site is not easily accessible to construction machinery, the cost of demolition and construction will be higher, showing the location impact on rebuild cost.

➢ Size and Design of the New Home

There is a land size impact on rebuild cost. The bigger the house, the more materials and labor are required. A double-storey house may occupy less land, but can have a higher knock down rebuild duplex cost because of the design and structural costs. The design features of high ceilings, large windows, and complex rooflines will add to the construction costs.

➢ Site Conditions and Soil Type

Low-quality soil could need more substantial footings or the use of engineering designs. Sloped blocks of land could raise excavation costs. Unforeseen problems that arise during the demolition process also increase expenses. Managing these challenges often depends on having the right team with strong essential construction skills for tradies, especially in site assessment and structural preparation.

➢ Material and Finish Selections

Material selection will have a significant influence on the overall cost. The use of basic materials will be cheaper compared to the use of high-end tiles, stone bench tops, and custom-made cabinets. The inclusion of energy-efficient features such as double glazing and solar panels will increase the overall cost but may lower future expenses.

➢ Council Requirements and Approvals

Local council rules affect project timelines and knock-down rebuild prices. Approval fees, design requirements, and inspection processes differ. Delays in the approval process may extend your project timeline, which may result in increased holding costs, such as rent or loan repayments.

➢ Temporary Living Arrangement

Temporary living arrangement is another factor to consider. During the demolition and construction process, you will require alternative accommodation. Renting for a few months will increase your overall costs. This stage of planning will help you cope with the financial stress during the construction process.
