What’s the difference between modular homes and conventional homes?

The major difference between modular homes and conventional homes is the way they are built. While conventional homes are built 100% on site, modular homes are built in a factory environment and then delivered to site for installation and fit-off. Plus, as the name suggests, modular homes are built in ‘modules’ for ease of transportation.

Are modular homes the same as kit homes?

No. While the end result may be similar, the way that modular and kit homes are purchased is quite different. When you purchase a prefabricated modular home, you are buying a complete home, installed onto your site and ready to move in to. When you buy a kit home, you are essentially paying for the working drawings and the raw materials – the owner is then required to handle the labour aspect of the build, including project management.

Where do you deliver your homes?

Our modular homes can be transported and installed almost anywhere within our area of service, which covers Victoria and parts of southern New South Wales. Please refer to the map on our home page to see if your land falls with our service area or contact our team directly to discuss.

How much does it cost to transport the home to my site?

The cost of delivery for your home to site is included in the base price. This is based on the most common route from our facility to your site, however, occaisionally it’s not possible to take the most common route as our trucks must take the over dimensional route. In these cases there may be additional delivery fees.

Are the permits and legal requirements the same as conventional homes?

Yes – the permit process is very similar whether you’re building a modular or conventional home. Depending on your circumstances you may require a planning permit – from our experience they are required in around 70% of builds. A building permit is required for all new homes that are built – both modular and conventional.

How long does it take to build a modular home?

Modular homes are fast to build – from the time construction starts in the factory until you move in usually takes around 14-18 weeks. This timeframe includes the factory building phase (8-10 weeks in the factory) and the on-site fit-off phase (6-8 weeks on your land).

Why should I consider building a modular home?

There are many benefits to building a modular home. They are faster to build, are often more affordable and have less of an environmental impact on your site. You have flexible options when it comes to design and it’s easy to up the energy rating and create a sustainable and eco-friendly home. You also get a complete package – your home comes with many inclusions and will be ready to move in and enjoy on completion.

Will I need to hire a local builder to complete the process or do you take care of this?

You won’t need to hire a local builder – our site team will take care of everything. While the production team are constructing your home in our factory, our site team will prepare the footings and connections on your site. They’ll get your home ready for delivery and when it arrives will spend 4-6 weeks on-site finalising the installation and adding the finishing touches.

How do I go about connecting electricity and other utilities?

This will depend on your site and is an important factor when choosing your land. If the block is serviced, consider the distance from your where your home will be built to the connections. If the land has no connections in place, you’ll need to include the added expense of connecting in your budget. Our team can visit your site to offer advice, and connections to services can be included in our scope of works.

Can I get finance on a modular home?

Yes. More than half of our clients require finance when building their new home. There can however be some challenges to obtaining finance for modular homes. Lenders can find it hard to progress payments while the home is being built off site, and may not want to release funds until the house is completed. This often comes down to a lack of understanding of modular homes, and can be overcome. Our team have helped hundreds of customers in a similar situation and are happy to share our knowledge, chat to your lender or recommend a broker who has experience with financing modular homes.

Can I alter or change standard plans?

Yes. While there are certain design parameters that need to be considered with our modular homes, we have over 40 standard modular homes designs that can be modified to better suit your requirements if required.

Do you build custom design homes?

Yes. We can custom design and build your dream home or adapt your existing design to our prefab modular home building system.

Are installation and footings included in the price?

Yes. Installation onto concrete footings up to 600mm depth is included in the base price given that your site is flat +/- 300mm over the building footprint.

What permits do I need for my home?

All new homes require a building permit and some will also need a planning permit. Planning permits, which are known as development applications in NSW, are compulsory in certain situations and must be obtained before construction begins. If your property is subject to any planning overlays, is within a bushfire zone or an area that is prone to flooding, has more than one dwelling on the block or has heritage considerations, it’s likely that you’ll need a planning permit. Building permits (or Complying Development Certificates in NSW) are issued once your home is built, inspected and found to be safe and built in accordance with the building code. All new homes, whether modular, kit or conventionally built, must have a building permit.

What is a 7 Star Energy Rating?

As part of the process to obtaining a building permit, new homes must have a minimum 7-star energy rating. Energy ratings on homes range from 1 to 10 – 1 being the least energy efficient, and 10 being the best. An approved energy rating consultant calculates the rating based on a number of factors including size, building orientation, insulation, shading, windows, and energy efficient lighting. Our homes are all built to a minimum 7-star energy rating, and there are many building sustainability upgrades that you can choose to include to further increase this rating.

What is a BAL Rating?

If you’re building a new home in Australia, it’s highly likely a BAL (Bushfire Attack Level) rating will be required. There are six BAL categories ranging from low to extreme. A BAL report can be completed by a fire assessor or engineer and they’ll base their findings on the Fire Danger Index, slope of the site, the type of vegetation surrounding the property and how close it is to your home. Your rating will impact on a number of factors when it’s time to build – if the BAL is over 12.5 there will be special requirements relating to materials used. Our standard modular homes are built to a BAL 12.5 rating – if a higher rating is required further upgrades can be added to meet the BAL rating for your site.

Can you build on BAL 40 & Flame Zone rated properties?

Yes, we can build to BAL 40. BAL 40 construction levels are achievable with modular homes, with substantial upgrades to construction materials, which are compliant with the provisions of the Australian Standard for construction of buildings in bushfire prone areas, AS 3959. No, we are not able to build to BAL FZ (Flame Zone).

What is a Bushfire Management Statement?

A Bushfire Management Statement (BMS) is a document required for building in areas at risk of bushfires. It outlines how your home and property will meet safety rules to reduce the risk of bushfire damage. This includes things like building materials, vegetation management, and access for emergency services. It’s an important part of the planning process to help protect your home and meet local council and CFA requirements.

A Land Capability Assessment (LCA) is a detailed assessment and report that is applicable if your property is located in an area that is not connected to sewerage. It identifies site features that will assist you in developing a management plan for your on-site wastewater management that will enhance long-term sustainability and minimise environmental impacts. The LCA will determine the best place for the installation of a waste water treatment system including the location of an effluent field.

How do I know if I can get a modular home onto my property?

Our friendly team are available for advice on access and location, plus, planning and reporting requirements too. We can perform a desktop assessment from our office or physically visit your property to report on its suitability. Assessment pricing is site-specific, and you can contact our team for a quote for your property.

Do you build on concrete slabs?

Unfortunately, because our homes are prefabricated in a factory, our building system requires our homes to be built on a steel floor frame therefore we cannot build a modular home in a concrete slab.

What type of warranty do your homes have?

All Anchor Homes come with a 7-year Home Owners Warranty. Plus, we also offer a 3-month building maintenance period after handover.

How do I know if I am eligible for the First Home Owners Grant?

To be eligible for the first home owners grant you must not have previously received a grant in Australia, not owned residential property before 1st July 2000, the property must be occupied as a home for a continuous period of 12 months within the first 12 months, plus, you’ll need to meet the residency requirements. If you have a partner or spouse, they must also have not received a grant or purchased property previously.

How do I choose the best facade for my project?

When choosing a façade, focus on harmonising with your home’s interior style while also complementing the surrounding environment. At Anchor Homes, our skilled team will help guide you when selecting your façade, cladding materials, and colour scheme to work with your overall vision for your dream modular home.

Can Anchor Homes create a custom facade for my project?

If you have a few creative ideas of your own, we can work with you to bring your own unique facade to life with our in-house architect.

What is the standard ceiling height for the Cubehaus facade?

The Cubehaus facade allows for 9ft ceilings throughout.

What is included in the Hamptons facade upgrade?

The Hamptons façade is an optional upgrade for the Avoca 12, Avoca 14, and Avoca 18 modular house designs. This upgrade includes: Double aluminium French doors, upgraded front door and handle, fretwork with cement sheet backing, painted timber window trim and ledges (3 sides of the home), additional area to home (1.8m2), additional gables, a portico, unlined skillion verandah, stacked stone piers, merbau decking (90mm) and linea cladding to all external walls (180mm).

Are your facades compatible with solar panel systems?

Yes, at Anchor Homes, all our standard facades are compatible with solar panel systems.

Do you design and build custom prefab modular homes?

Yes — Anchor Homes specialises in the design, construction, and delivery of fully custom prefab modular homes. With over 20 years of expertise in modular home design, we have proudly helped hundreds of clients across Australia realise their vision of a beautifully crafted, bespoke prefab modular home.

Do you have an in-house architect?

Yes — Anchor Homes is proud to have Chris Stoik as our dedicated in-house architect. With an impressive depth of experience in custom modular home design, Chris works closely and personally with each client to understand their vision and translate it into a refined design that performs beautifully within our modular building system.

Can your architect help me create a concept from scratch if I don't know what I want?

Yes — and this is where we truly excel. Many of our clients arrive with a lifestyle in mind rather than a finished design, and that is entirely welcome. Our in-house architect Chris Stoik will work closely with you through a thoughtful and collaborative design process. He will take the time to understand how you live, what you value, and what you aspire to achieve before developing a bespoke custom modular home design from the ground up, tailored entirely to your vision, your site and your budget.

How do I start the process of building a custom modular home with Anchor Homes?

The first step is to reach out to our team via the contact page on our website or give us a call on 1300 946 815. One of our experienced project consultants will be in touch to personally guide you through the custom modular home journey.

From there, we take care of everything!

Can you work with my own architect or designer?

Anchor Homes primarily works with our in-house architect on all custom modular home projects, as designing a prefab modular home demands an intimate understanding of our construction methodology as well as transport and structural requirements. That said, we are happy to work alongside your architect or designer. Due to the nuances of modular construction, our team would still prepare the final drawings and documentation to ensure everything meets our precise building standards. The good news? Everything you need is right here under one roof.

Can you convert my architect's plans to modular construction?

Yes — if you have existing drawings, whether for a traditionally built home or a modular design, our in-house architect will carefully assess and adapt those plans to suit our modular building system. Some modifications may be required to ensure the design is fully optimised for our construction methodology, and our team will walk you through any changes with complete transparency. Throughout the process, we are committed to staying as true to your original design intent as possible.

Will my custom modular home look any different to a traditionally built home?

No — A custom prefab modular home designed and built by Anchor Homes is virtually indistinguishable from traditional site-built construction. Our homes are crafted and finished to the highest standards, with the full breadth of architectural styles, premium materials, and refined interior finishes available to you.

How much does a custom prefab modular home cost?

As every custom modular home is entirely unique, pricing is tailored to each individual project. The best way to understand costs for your project is to submit an enquiry on our website. From there, one of our project consultants will arrange a dedicated discovery call to understand your vision, design aspirations, and build location, before preparing a clear and transparent sales estimate for your review.

Knock-Down Rebuild Prefab Homes in Victoria 2026 | Anchor Homes

Modular construction

August 05, 2026

Written by

Alana McNab

More Victorian homeowners are considering knock-down rebuilds, but now discovering there is a smarter way to do it than the traditional pathway.

💡The answer: prefab modular homes.

The appeal for a knock-down rebuild is easy to understand. The location is right and the neighbourhood is right, but the house no longer suits the way they live. Rather than compromise with a renovation or leave a place they love, more homeowners are replacing an ageing dwelling with a new home designed around their family. What has changed is that this can now be done faster than before, without compromising on quality or style, thanks to prefab modular construction.

So what does that mean in practice? It changes how the new home gets built. In place of a traditional on-site build, with its longer timelines and exposure to weather and site conditions, a growing number are turning to prefab.

Knock-down rebuild prefab homes bring the precision of a controlled off-site build to established suburbs and rural blocks alike. And there is no trade-off in the finished home: a prefab modular home from a builder like Anchor Homes is built to meet the same standards and codes as any traditionally built home.

This guide walks through how the process works, what to budget in 2026 and how to choose the right prefab modular home builder.

What is a Knock-Down Rebuild Prefab Home?

Let's discuss how it works.

A knock-down rebuild involves demolishing your existing house and constructing a brand new home on the same land. When that new home is prefabricated, the bulk of the build happens inside a controlled off-site facility rather than on your block. In simple terms:

1. Demolition clears the existing structure and prepares the site. This can run in parallel while the off-site construction is taking place, speeding up the project timeline.

2. Off-site construction builds your new home in modules, quality-checked in a established manufacturing facility.

3. Delivery and installation sees the completed modules transported to site and craned into position.

4. On-site completion connects services, finishes joins between modules, and readies the home for handover.

It is a different path to a renovation. Home renovation projects work within the bones of an existing building, which can mean compromise, hidden surprises and costs that shift as walls come down. A knock-down rebuild gives you a clean slate and a home built entirely to current standards.

Why Prefab Suits Knock-Down Rebuilds

A knock-down rebuild asks a lot of a build.

You are working on an established block, sometimes in a tight suburban street and sometimes on rural acreage, with neighbours and existing services to consider. Prefabricated housing solutions are well matched to those conditions, and to the demands of Victorian sites more broadly, for several reasons:

✔ Faster build timelines.

The build itself is much shorter than a traditional on-site project. A conventional knock-down rebuild typically spends 10 to 18 months under construction, whereas a modular home is built, installed and ready for handover in roughly 4 to 5 months, depending on the scale of the project.

On top of that, the work overlaps: while demolition, footings and services are handled on your block, your home is already being built off site, taking further weeks off the overall program.

✔ Quality-controlled construction.

A dedicated off-site facility delivers precise, repeatable results, with finishes that are not left to the mercy of weather or site conditions.

✔ A clear picture of costs.

Pricing is set out from the start, so you can plan the whole project with confidence rather than bracing for mid-build surprises.

✔ A managed council and planning process.

Anchor Homes can handle the planning and building approvals on your behalf, coordinating the documentation so compliance does not fall to you.

✔ Flexible design options.

Modify one of our existing floor plans or develop a fully custom brief with our team, so the finished home suits your block and the way you live.

✔ Less disruption to your street and neighbours.

Most of the noise, traffic and mess happens off site, with the on-site works compressed into a much shorter window. In established suburbs, that is a real advantage.

✔ A more sustainable build.

Building off site is more resource-efficient than a traditional on-site build. Materials are measured and cut precisely, offcuts can be captured and reused, and far less waste ends up in landfill.

✔ Suited to sloping and challenging sites.

Many blocks in Victoria are not flat, and a sloping site calls for a home that works with the terrain rather than against it. Custom prefab construction responds to the fall of the land through split levels, elevated decks and considered module placement

✔ Bushfire compliance where it is needed.

Homes can be engineered to meet the relevant Bushfire Attack Level (BAL) requirements, which matters across much of regional Victoria.

The Knock-Down Rebuild Process

A prefab knock-down rebuild follows a clear sequence. Knowing the order helps you plan with confidence.

1. Free Desktop Site Assessment: | Start here →

Clients speak with an Anchor Homes project consultant about their vision, their block and what they are hoping to achieve. The team completes a desktop site assessment and advises on suitable designs and realistic scope before any fees are incurred. There is no obligation, just clear advice on what is possible for a specific block and project budget.

2. Complimentary project proposal:

Anchor Homes prepares a detailed project proposal covering estimated construction costs, upgrade options and pre-construction fees, so clients have a clear investment picture before committing to anything. Once they are happy to proceed, they sign a pre-contract agreement and pay the pre-construction fee, which begins the pre-construction phase of the build.

3. Pre-construction phase:

Pre-construction is everything that happens before any part of the home is manufactured. It is the phase where every piece of documentation needed to build the home is compiled, coordinated and finalised. Essentially, the entire home is resolved on paper first, which includes:

• Architectural drawings

• Structural design

• A feature and level survey

• A soil report

• A wind classification

• A Bushfire Attack Level assessment

• An energy rating

• Colour, finishes and specification

• Council permits

Once this is complete and the homeowner is satisfied to proceed, the building contract is signed. That is the point at which construction begins on the new home in Anchor Homes' off-site manufacturing facility in Stratford, Victoria.

4. Off-site construction:

One of the real benefits of a knock-down rebuild is that the new modular home can be built off site while the homeowner is still living in their existing home, saving time and relocation costs. The home is built in Anchor Homes' off-site manufacturing facility, with the frame, lock-up and fixing stages completed while the site is prepared in parallel.

When it is time to demolish the existing home, the services need to be abolished beforehand. Demolition usually takes place once the building permit has been issued, at a time that suits the homeowner, which Anchor Homes helps plan around the build schedule.

Once the block is cleared, Anchor Homes prepares the site for the new home. This is the core advantage of modular: the new home takes shape while the block is being readied, rather than one after the other.

Throughout this stage, homeowners receive weekly photos and updates, and are welcome to arrange a visit to the facility at any point during the build.

5. Delivery and on-site construction:

Once the new home is 90 to 95% complete in the facility, it is prepared for delivery. The modules are transported to the block by truck and installed onto the prepared site, by crane or direct placement via truck depending on the project and access.

The Anchor Homes team then completes the final 5 to 10% of on-site works, including plastering, painting, service connections, staircases and finishing, and a building surveyor conducts the final inspection.

6. Handover:

A final walkthrough confirms everything is completed to the homeowner's satisfaction, the Occupancy Permit is issued by the building surveyor, and the keys are handed over. The new home is ready to live in and enjoy.

What Does A Knock-Down Rebuild Cost in 2026?

Every knock-down rebuild is different, so rather than a single figure, it helps to understand the costs to allow for when you plan your budget.

The main factors to consider are:

• Demolition. The cost depends on the size of the existing home, access to the site and whether asbestos is present, with two-storey homes and tight access sitting at the higher end.

• Asbestos removal. Homes built before 1990 should be assumed to contain asbestos until tested. Allow a separate provision for licensed removal.

• Service disconnections. Abolishing gas, electricity, water and telecommunications to the existing home.

• Permits, surveys and reports. Planning and building permits, engineering and soil testing, and energy assessments, with more required in overlay areas.

• Construction. This is the largest part of your budget, and it varies between builders depending on design, inclusions and finish. Because standard inclusions differ from one builder to the next, it is worth comparing on a like-for-like basis. You can view our price list and read our three-step guide to comparing home builder prices and quotes before you decide.

• Site costs on sloping blocks. Engineered footings, retaining and drainage should be factored in early, as the slope of your block influences the overall cost. Our guide to building on a sloping block covers what to plan for.

Frequently Asked Questions

Can you do a knock-down rebuild with a prefab home on a sloping block?

Yes. Sloping sites are one of prefab's strengths. The design can respond to the fall of the land through split levels and considered module placement, while the off-site build keeps the project on track despite complex groundworks.

Is a prefab knock-down rebuild faster than building on site?

Generally yes. Because your home is built off site while demolition and site works happen in parallel, the overall program is often shorter than a comparable on-site build.

Where does Anchor Homes build?

We deliver our modular homes across Victoria, Southern and Central New South Wales, and the ACT, with our off-site facility in Stratford, Victoria.
