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.

Off-grid living has come a long way! 🌱🏠

What was once considered a niche lifestyle choice has become a genuinely compelling option for Australians who want to live more sustainably, take control of their energy use, and build something that truly reflects their values.

And when you combine off-grid living with prefab modular construction, the result is something remarkable: homes that are beautifully designed, built with real precision, and capable of running entirely on their own.
In this article, we're taking you inside three of our favourite off-grid modular home projects, built by Anchor Homes for real clients across Victoria and New South Wales. We'll also walk you through what off-grid living actually involves and what to consider before building.

Whether you're considering an off-grid build or simply curious about what a sustainable modular home can look like, there's plenty here to get into.

What Does "Off-Grid" Actually Mean?

At its core, living off the grid means your home is not connected to, or reliant on, external utility networks for its essential services.

Rather than drawing power from the mains, drinking from a town water supply, or connecting to a sewerage system, an off-grid home generates and manages all of these things independently on-site.

In practice, that typically looks like:

⚡Energy: A solar panel system with battery storage, backed up by a generator for extended low-sun periods

💧Water: Rainwater collection tanks sized to meet household demand, with on-site filtration and treatment

♻️Wastewater: An on-site sewage treatment system appropriate for the land and local council requirements

The important thing to understand is that a well-designed off-grid home can be every bit as comfortable and functional as any other home. When every system is considered from the ground up, the result is a home that genuinely works, without compromise.

Why Prefab Modular Homes and Off-Grid Living Go Hand in Hand

For most people drawn to off-grid living, the dream involves space, nature, and a genuine sense of escape. That usually means rural or semi-rural land, which is wonderful in every way except one: building there with traditional construction methods can be complicated, time-consuming, and expensive. Trades are harder to source, site access can be challenging, and the costs of an extended on-site build in a regional location add up quickly.

This is where prefab modular homes come into their own. Because the vast majority of the build happens in a controlled manufacturing environment before anything arrives on-site, the challenges that come with remote and rural locations become far more manageable. It's one of the reasons Anchor Homes has become a go-to for clients building off-grid across Victoria and New South Wales.That said, off-grid living isn't exclusive to the country. Whether you're on a rural property, a semi-rural lifestyle block, or simply a site where connecting to services isn't practical or desirable, modular construction offers the same advantages. Here's why it works so well:

♻️ Less site disruption: The majority of the build happens in our manufacturing facility, minimising on-site activity and reducing the impact on the land around your home.

🔨 Predictable + coordinated build: Everything is managed centrally from our manufacturing facility, so there are no surprises on-site and no delays waiting on trades. You know what's happening, and when.

⏱️ Faster build timeline: By the time your home arrives on-site, it's already around 95% complete. Delivery and installation typically takes just one day, making for a remarkably smooth and efficient build experience.

🌿 Designed with sustainability in mind: Anchor Homes designs are built around sustainable design principles from the outset. Orientation, insulation, glazing, and thermal performance are all carefully considered, which matters even more when your energy supply is self-generated. All of our homes are built to a 7-star energy rating as standard, with higher ratings available on request.

✅ Proven capability on complex sites: Our team has delivered off-grid modular homes across Victoria and southern New South Wales, including in bushfire zones, on elevated rural blocks, and in locations with no existing service connections. We understand what these sites require, and we have the experience to get it right.

3 Best Off-Grid Prefab Modular Home Projects

1. The Arawata Project — VIC

Design: Newhaven 21 (Modified) · Bed: 3 · Bath: 2 · Area: 207sqm

Set among the rolling hills of South Gippsland, the Arawata Project is a barn-style modular home that makes an immediate impression. The clients had previously worked with an independent architect to develop a design they loved, but as they explored different ways to bring it to life , they found Anchor Homes offered a smarter path forward without sacrificing what mattered most to them.

Our design team reviewed the original plans and reinterpreted the design through our modular approach, using the Newhaven 21 as the foundation for a highly customised result. The outcome is a home that feels bespoke, sits beautifully in the landscape, and runs completely off the grid.

2. The Berridale Project — NSW

Design: Hampton 19 (Modified) · Bed: 4 · Bath: 2 · Area: 181sqm

Nestled in an elevated position surrounded by native bushland near the Snowy Mountains, the Berridale Project makes a strong case that off-grid living and genuine luxury are not mutually exclusive. This customised Hampton 19 was designed and executed to the finest detail, with every decision shaped by its remote, self-sufficient brief.

The home's orientation was carefully considered to maximise solar gain, with a raked ceiling and highlight windows drawing in natural light and warmth across the seasons. A large walk-in pantry keeps the home well-stocked and practical for rural life, while the expansive deck opens out to breathtaking alpine views. A refined, comfortable family home that operates entirely independently from the grid.

3. The Eganstown Project — VIC

Design: Flinders 17 · Bed: 4 · Bath: 2 · Area: 159sqm

Just five minutes from the charming town of Daylesford, the Eganstown Project shows what genuine off-grid commitment looks like in practice. With no existing service connections on the block, Anchor Homes designed and built this home to be entirely self-sufficient from day one. It runs on a solar power system with battery storage, collects and treats its own rainwater through on-site tanks and a pump system, and manages wastewater via a septic system.

The site also sits within a BAL-29 bushfire zone, so a large rainwater tank was incorporated to meet those requirements, and James Hardie Axon Cladding was specified in Monument for durability and resilience in the bushland setting. Despite the technical demands of the site, the finished home feels warm, considered, and anything but compromised.

Key Things to Consider Before Going Off-Grid

The projects above show what's achievable. Before you get started, here are the most important practical things to work through.

📍Land and location: Not all land is equally suited to off-grid living. Before purchasing, speak with your local council about planning permits, zoning overlays, and any specific requirements around on-site energy, water, or wastewater systems. The block should also be large enough to comfortably accommodate the infrastructure required. Not sure where to start? Submit a free desktop site assessment and our team can help you understand your site and what questions to ask before you commit.

⚡Solar and energy: Solar is the most common and cost-effective energy solution for off-grid homes in Australia. You'll need to estimate your household's daily energy use to size the system correctly. Panels, battery storage, an inverter, and a backup generator are all part of a complete setup.

💧Water supply: A rainwater collection and storage system, sized for your household and local rainfall patterns, is essential. Water will need to be treated before drinking, typically through UV disinfection or similar methods. Anchor Homes can arrange these associated infrastructures as part of your build, so it's one less thing to coordinate yourself.

♻️ Wastewater: An on-site sewage treatment system that meets local council requirements is a must. This is often one of the more significant upfront costs and is worth planning carefully from the start. Anchor Homes can organise septic systems and wastewater solutions as part of your project, ensuring everything is compliant and properly integrated.

🌿 Sustainable design: Getting orientation, insulation, and glazing right reduces how hard your off-grid systems have to work. At Anchor Homes, sustainable design principles are built into every project from the very first conversation.

For a deeper dive into each of these areas, our article Living Off Grid in Australia covers them in detail.

Build Pre-Designed or Custom

Every Anchor Homes design in our pre-designed range can be built as an off-grid home.

Whether you're drawn to the barn-style Newhaven, the classic Hampton, the contemporary Flinders, or any other design in our range, our team can configure the right off-grid systems to suit your site and lifestyle.

If you have something more unique in mind, our our in-house architect works with clients on fully custom off-grid home designs. From the floor plan to the facade to the self-sufficient systems that keep it running, custom off-grid homes are something we genuinely enjoy getting into.
