Knock it down, then build again!
- Knockdown Rebuild


What should you do if you live in a great location but your house is far-from-ideal?
Welcome to the idea of knockdown rebuild!
Whether you’ve outgrown your current home or whether your house has seen better days, starting from scratch can save you time, energy and money. Knockdown rebuild is an ideal way to get a home you love where you already live.
A knockdown rebuild is pretty much exactly what it says on the tin: the owner of an existing house chooses to knock it down and then build a new home on the same block of land. It might even be that someone buys a house knowing from the outset that they’ll demolish what’s already there in order to build their ideal home in that location.
For someone wanting to live in a different home than they are currently, knockdown rebuild is an alternative to either moving to an entirely different house in a different location, or doing extensive renovations.
Knockdown rebuilds are popular especially in established suburbs, where the chances of finding an empty block to build on are almost zero. And for people who are established within their community so don’t want to lose those connections by moving further afield.
It’s not only homeowners who choose to knockdown and rebuild. Investors can add equity to their portfolio and save on the costs associated with maintaining older properties.

Let’s step our way through what to expect when you knockdown, then rebuild your home:
1. New home design: Before a wrecking-ball gets anywhere near your current house, it’s wishlist time! You start by focussing firmly on the end. Yes, that’s right, the first step of a knockdown rebuild process is you spending time choosing your home’s overall design - think floorplan, facade, materials and colours. Then, focus on the fixtures and fittings. This is the time to dream big and focus on both creating and future-proofing your dream home.
2. Knockdown: It’s demolition time! But the knockdown only commences once all the paperwork is complete, experts are consulted about important elements like trees and service disconnections. Safety is the number one priority, including consideration of asbestos or other hazardous materials.
3. Rebuild: You’ve already done the decision-making work so now it’s time to sit back and watch your new home come to life. If you’ve trusted Rawson Homes with your knockdown rebuild process, you’ll have a Site Manager to keep you updated on progress as it happens.
4. Move day: This is the moment where your plans come together as you put the key in your new front door and start to enjoy the fruition of your knockdown rebuild!
What are the pros and cons of knocking down and rebuilding your home? Let’s go…

If your current home isn’t meeting you and your family’s needs, you essentially have four options:
At first glance, renovating might seem like the easiest and lower stress option of the three. However, it’s well known that it’s very common that renovation costs and timelines blow out significantly.
Moving to a completely different house might be appealing as timelines are shorter, even factoring in the time spent house-hunting and then the settlement period. However, if you can’t find an ideal home within the same suburb, your move will be followed by a loss of connection to your previous community and changes to everything from schools to your favourite local cafe.
Buying land in a greenfield area (where there were no existing houses) and building can be an exciting journey to embark on, as long as you’re prepared to move to a new area and wait for your new home to be ready.
So, it’s well worth considering undertaking a knockdown rebuild. You might be heartened to know that you’re far from alone, as almost a third of all newly built homes in Australia result from knocking down the old before building the new.
You might assume that demolishing a house and then building from scratch might be far more expensive than simply buying a different existing home, or doing big renovations. However, that’s not always the case.
One big financial bonus of choosing a knockdown rebuild over buying a home elsewhere is that you’ll not pay any stamp duty, saving you tens of thousands of dollars!
As each knockdown rebuild is an individual project, it’s not really possible to offer an ‘average cost’ of a knockdown rebuild, as costs can vary significantly at each stage of the process.
Demolition costs vary depending on the size of the existing home, the number of other buildings, like sheds or garages, the complexity of services, the complexity of the block of land and the need for safety elements like temporary fencing and traffic management.
Local council and other approvals will vary in cost depending on where you live. And then, of course, there’s the construction costs, which will be vastly different depending on the size you choose for your home and whether you go with a pre-planned design or prefer a more tailored floorplan.
Another important cost factor is what your chosen builder includes in a standard knockdown rebuild contract (or tender). Make sure you’re clear on whether costs like soil testing, stormwater drains, sewer connections and driveways are included. These are all included in Rawson’s knockdown rebuild tenders so, if another builder doesn’t factor these in, you’ll need to add some big numbers onto your quoted price.
We outlined above how costs will change depending on the scope of the knockdown rebuild process. Similarly, it’s not possible to give a general estimate of how long a knockdown rebuild process will take. Timings depend on how long you need to make your design decisions, how long council approvals take and the availability of materials.
As a guide though, from initial design through to completion, most people move into their newly built home in 1-2 years of getting started.
Choosing the right builder is a vitally important step. We suggest you speak with a few builders to find out how they work and ask important questions, including how experienced they are with knockdown rebuilds, whether they offer a fixed-price tender, what eco-friendly elements are available, how much say you can have in the design and choices of fixtures and fittings.

Given the number of variables involved, it’s not possible to give an absolute answer about whether it’s cheaper to renovate a home, buy elsewhere, or to knockdown and rebuild on your existing land. However, with a fixed-price tender, the cost of a knockdown rebuild can be agreed to from the outset, providing certainty compared with renovations, which are notoriously hard to cost proactively.
A knockdown rebuild project includes multiple stages: new home design, approvals, demolition and building. You’ll also need to factor in alternative accommodation for during the build. A good knockdown rebuild specialist builder will work with you to calculate all the costs of your particular project, giving you a sense of certainty.
A conversation with your bank will be needed to determine whether you have access to funds to cover both your existing mortgage and the costs of a knockdown rebuild.
To determine whether you can undertake a knockdown rebuild, your bank will look at the equity you have in your home and your personal financial situation, as well as the costs of demolition and construction.
