Knockdown Rebuild Specialists Melbourne
Start Fresh Without Leaving Home
Love your street but not your home? A knockdown rebuild gives you a brand-new custom home on the land you already own, without the compromise of renovating around old bones.
Tear Down. Build Up.
A knockdown rebuild means demolishing your existing home and replacing it with a completely new, custom-designed build on the same land. It’s a great solution if you love your suburb or your neighbours, but just feel like you’ve outgrown your home. You keep the block and the lifestyle, and we take care of everything else from demolition through to handing over the keys.
A Knockdown Rebuild Makes Sense When…
01
Your home is past its prime
Structural issues, inefficient layouts, or decades of deferred maintenance mean renovation costs are starting to outweigh what you'd actually gain. Starting fresh can often be the smarter approach.
02
You love your location
The right suburb can take years to find. A knockdown rebuild lets you stay near the schools, parks, and community you've built your life around.
03
You want complete control
Unlike buying or renovating room by room, a new build gives you full say over every detail. You can design everything from the floorplan to the finishes entirely around how your family lives.
04
Your family has changed
A home that worked decades ago may not work today. This is your chance to design a home that reflects who your family is now, and where you're heading.
05
You want energy efficiency
Older homes can be expensive to run and difficult to retrofit. A new build lets you start from scratch with modern insulation, glazing, orientation, and systems that keep running costs low.
06
You’re thinking about value
In many Melbourne suburbs, a well-designed new home significantly outperforms the value of an older dwelling on the same land, making a knockdown rebuild a sound long-term investment.

From Demolition to Dream Home
We handle every step from permits and planning to handover. Here is what to expect when you work with Allgrange.
-
A knockdown rebuild comes with a lot of questions and concerns, which is why we always start with a conversation. Tell us about your block, your vision, and how your family lives. We'll give you an honest picture of what's involved and whether a knockdown rebuild is the right path forward.
-
We work alongside you — and your architect or designer if you have one — to develop a design that suits your block, your lifestyle, and your budget. This is a collaborative process where your ideas are welcomed and guided by our expertise.
-
Our team manages the full demolition process safely and efficiently, including any required disconnections and site preparation. We keep you informed throughout so you know exactly where things stand.
-
Once construction begins, your home progresses through key stages, each carefully managed and scheduled. We keep you informed of progress so you always know how your home is advancing. During this process, you’ll be invited to walkthroughs and selection meetings where questions are encouraged.
-
It’s time to move in! Before you receive your keys, we complete some final checks to ensure everything is ready. Your home is backed by a 10-year structural warranty, and we remain available to assist during the maintenance period after move-in.
Clear Communication From the Start
You've probably heard the horror stories about builders disappearing once construction starts and decisions being made without consultation. We want you to feel confident in your investment, which is why clear communication is a core part of our service.
It starts with transparent quotes explained in plain language. Once construction begins, you'll receive regular progress updates and invitations to check-ins and walkthroughs at key milestones throughout the build.
You'll always have a dedicated point of contact to make sure your questions are answered as soon as you think of them. And if changes or variations arise, we discuss them openly, explain cost or timeline impacts, and seek approval before proceeding. No surprises, no pressure.
We treat good communication as a core part of our service, not an afterthought.
