Wondering how our knockdown rebuild service works? From our pre-construction process to your move-in day, McCarthy Homes takes the lead in ensuring your knock-down rebuild is as smooth as possible, and that the designs meet your expectations.
Our Process
Pre-Construction
We sit down with you and your family to discuss the vision you have for your new home and your design preferences. We also conduct a thorough site assessment to identify potential challenges before construction begins.
Knock Down
Once building approval is received, we use a licensed demolition contractor to knock down the existing structure to create your new home. Once complete, we prepare the land for construction.
Rebuild
Based on your preferences and pre-approved designs, we get to work on building a new home for you and your family in the exact same spot. From laying the foundation to final fittings and quality checks.
Move In!
Before we hand over the keys, we take you for one final walk-through to ensure everything is exactly how you envisioned. Once confirmed, it’s time to move into your brand-new house in the same area you know and love.
Why knock down and rebuild?
As your family grows and lifestyle changes, your existing home may not offer everything you want. But if you already love where you live then there’s no need to move – a knock-down rebuild means you can stay right where you are.
Rebuilding on your own land allows you to stay within easy reach of friends, family, work and your favourite amenities. A rebuild also offers far more flexibility than a renovation, so you can turn an outdated house into a modern custom-built masterpiece.
If you’re happy right where you are, a knock-down rebuild can bring an abundance of lifestyle, comfort and convenience — and McCarthy Homes is here to deliver just that. Our knockdown rebuild specialists are here to guide you every step of the way, and ensure your dream home becomes a reality.
“We are so happy with our new home and we feel very proud to show it off to all our friends and family”
The house was finished off beautifully and so much care was taken that you would have thought we were the only people McCarthy’s were building for at the time. The job was even finished two weeks earlier than planned which meant we were able to have our landscaping and driveway completed before Christmas.
We are so happy with our new home and we feel very proud to show it off to all our friends and family. We also get a real kick when people driving past slow down to have a look.
To anyone wanting to build a home you can be proud of, to work with such caring people that they feel like family, then you can do no better than McCarthy Homes. We wholeheartedly recommend McCarthy Homes.

We would highly recommend McCarthy Homes to anybody seeking a quality builder. Our experience building with McCarthy Homes was exceptionally positive, from contract through to hand-over stage. Six years on we love our McCarthy Home now more than ever and continue to receive very positive feedback from visitors about the quality of workmanship and finishings in our home, and its ‘perfect’ layout. McCarthy Homes will definitely be our builder of choice should we build again in the future.

“This is our fifth home we’ve built over the years and this one has been hassle free.”
We are so happy we built with McCarthy Homes. This is our fifth home we’ve built over the years and this one has been hassle free. Once the plans came out from council, our Site Supervisor was introduced to us and we had a wonderful relationship in the building process. We were kept appraised each step of the way and the time frames he offered were met. At our six month maintenance, there were only a few minor items to be addressed and they were attended to without fuss. The quality of the workmanship has been great – we haven’t even had cracks in the plaster cornices! If I was to consider building again, I would certainly look at what McCarthy can do for me. Kind regards.

Knock-Down Rebuild FAQs
What is a knock-down rebuild?
A knock-down rebuild is a type of new home construction that involves demolishing an existing house to rebuild a new one in its place. Knock down rebuilds are an affordable alternative to major renovations or purchasing vacant land for your project.
How much does it cost to demolish a home in Brisbane?
It typically costs between $15,000 and $30,000 to demolish a home in Brisbane. This price includes planning fees and site costs, such as waste removal and the demolition of features like driveways and concrete slabs. Many people finance their knock-down rebuild with a construction loan tied to a building contract.
Demolition fees are the only major additional cost that comes with a knock-down rebuild when compared to a new build. The cost of the demolition is offset by the money you save on stamp duty, agent’s fees and the other expenses that come with moving to a new property.
How long does it take to demolish a house?
It only takes 1-2 days to demolish a house, depending on the size of the property and whether the demolition company needs to deal with issues like asbestos. The full demolition process takes approximately 2 months. That time is used to plan the project, obtain council approval, demolish the house and clear away the unwanted materials.
How long does a knock-down rebuild take?
A complete knock-down rebuild takes approximately 8-12 months from start to finish, depending on your demolition contractor. This process takes slightly longer than building on a vacant block of land because of the extra time required for demolition. The time it takes to complete your project depends on the layout of the new home, custom features you want, council approvals and whether any challenges arise along the way.
Is it better to renovate or knock down and rebuild?
A knock down rebuild is typically the better option if you are considering major home renovations. Rebuilding your home gives you complete freedom to design a property that’s perfect for your lifestyle. It also adds value to the home, improves energy efficiency and comes with less financial risk than a renovation or extension.
If you’re only planning minor changes or a small extension, renovation may be the better option for you.
Who organises demolition for a knock-down rebuild?
You are responsible for organising demolition during a knock down rebuild project. This gives you the freedom to compare quotes and choose a demolition contractor that’s available when you need them.
