Knockdown Rebuild in Melbourne with Omnia Homes: Everything You Need to Know

Knockdown Rebuild in Melbourne with Omnia Homes: Everything You Need to Know
Joel RobinsonApr 28, 20255 min read

If you’re considering a knockdown rebuild in Melbourne, you’re not alone. More and more homeowners are opting for this approach, and it’s easy to see why. 

The benefits of tearing down an old home and rebuilding a new one on the same site can be significant, from increasing your property’s value to creating a space that’s perfectly tailored to your needs. 

Omnia Homes, an industry leader in this space, is known for its expertise in guiding homeowners through the knockdown rebuild process.

What is a Knockdown Rebuild?

A knockdown rebuild involves demolishing your existing home and rebuilding a new one in its place. This process allows homeowners to stay in their existing location, which might be in a desirable neighbourhood, while upgrading their living space to meet modern needs and standards. 

It’s a smart alternative to moving to a new home, as it enables you to enjoy the benefits of a brand-new house without the hassle of changing your address.


Understanding the Knockdown Rebuild Process with Omnia Homes

Omnia Homes offers a streamlined approach to knockdown rebuild projects, ensuring a smooth, stress-free experience. Their process is well-defined, making it easy for homeowners to understand what to expect at every stage of the journey.

1. Initial Consultation and Design Phase

The first step is a consultation with Omnia Homes, where you'll discuss your vision, budget, and expectations. 

Omnia Homes offers over 85 existing floor plans to choose from, or you can fully customise a design to suit your needs. 

If you already have your own drawings, they’re happy to work with those as well.

2. Obtaining Permits and Approvals

Once the design is finalised, Omnia Homes will guide you through the process of obtaining all the necessary permits and approvals. This includes council approvals, demolition permits, and construction permits. 

With their extensive knowledge, Omnia ensures that navigating the often-complex planning regulations is smooth and efficient.

3. Demolition

Once the permits are in place, the demolition of your existing home begins.

Omnia Homes works with trusted partners to ensure that the demolition process is carried out safely and responsibly, with proper recycling or disposal of materials. They manage this process for you, so you don’t need to worry about coordinating the details.

4. Building Your New Home

With demolition complete, the construction of your new home begins. 

Omnia Homes takes great pride in delivering high-quality work, using only reputable suppliers and skilled tradespeople. 

During the build, you’ll receive regular updates and site visits to monitor the progress. 

Omnia is known for its commitment to delivering homes within agreed timelines. They offer guaranteed build times: single-storey homes typically take around 5.5 months, and double-storey homes just under 7.5 months.



5. Final Inspection and Handover

Once construction is finished, a final inspection is conducted to ensure that everything meets your expectations. 

Omnia Homes' building supervisor will walk you through the final inspection before handing over the keys. They also offer ongoing aftercare service to ensure you’re fully satisfied with your new home.

Costs of a Knockdown Rebuild in Melbourne

One of the most common questions homeowners ask when considering a knockdown rebuild is, “How much does it cost?” 

The cost of a knockdown rebuild can vary significantly depending on several factors, such as the size of the home, the complexity of the design, and the site conditions.

The cost in metropolitan areas such as Sydney and Melbourne is generally higher than in regional areas, due to factors like higher labour costs and permit fees on top of the specific preferences and specifications of the new build.

Basic rebuilds in Australia start from around $300,000, while high-end projects can exceed $1 million. Omnia Homes offers a range of custom home designs that can fit different budgets, from more affordable options to premium, luxury builds.

It's also important to note that demolition costs, council fees, and other associated expenses will add to the overall price. Omnia Homes offers True Fixed Price Quotes, ensuring no hidden costs and full transparency about the total project cost, from design through to handover.


How Long Will the Knockdown Rebuild Process Take?

The duration of a knockdown rebuild can vary, but on average, the entire process typically takes between 12 to 18 months. This includes design, council approvals (which can take 3 to 6 months), demolition (a few weeks), and construction (6-12 months, depending on the complexity and size). 

Several factors can impact the timeline, including the complexity of the design, site conditions, council approval delays, and any unexpected issues that arise during construction.

You should also consider the possibility of needing temporary accommodation while your existing home is demolished and the new one is being built. A temporary accommodation can add to your overall budget as the process unfolds.

Omnia Homes offers a certificate with guaranteed start and finish dates, providing you with clarity and assurance throughout the rebuild process.


Legal Requirements and Building Codes for Knockdown Rebuilds 

Before starting your knockdown rebuild journey, it's crucial to be aware of the legal requirements and building codes that apply in Melbourne

Omnia Homes works closely with local councils to ensure that all necessary permits and approvals are obtained before the demolition and construction phases begin.

In Melbourne, a knockdown rebuild must comply with zoning laws, environmental regulations, and building codes, including the National Construction Code (NCC). These codes cover areas such as structural integrity, fire safety, accessibility, and energy efficiency. 

Omnia Homes ensures that your project meets all these requirements, giving you peace of mind that your new home will be built to the newest and highest legal and safety standards.


Ready to Start Your Knockdown Rebuild Journey?

A knockdown rebuild with Omnia Homes is an excellent way to create a custom home that perfectly suits your needs while staying in the Melbourne location you love. 

The process offers the chance to design a space that’s truly yours, without the stress of moving or the uncertainty of major renovations. 

With clear guidance, transparent pricing, and a focus on quality, Omnia Homes ensures the journey is as smooth and straightforward as possible. 

If you're considering a knockdown rebuild, it’s worth exploring the options and understanding how this approach can help you achieve your ideal living space.
