Building your dream home can be a daunting prospect no matter which way you look at it. New modular prefab homes are quickly becoming a popular way to build homes across the country. Here’s what you need to know before you choose one…

Perhaps it’s time to think differently about the way we build our homes. With consumers expecting instant gratification, combined with emerging advances in building processes, it seems only sensible to see if we can be more efficient with house construction.
Beyond the standard building processes, there are more options open now for home builders. The main two are kit homes, which generally have pre-cut/prefabricated materials supplied and are built onsite; or modular/prefab homes, which are completely built in a factory and then delivered to site.
Unlike traditional homes and builds, prefab homes are a more efficient and speedy way to create homes. With the modular homes built off-site in specialist facilities and then moved into place, the process of building these homes can be more simple and cost-effective while also boasting more eco-friendly credentials.
Indoor-outdoor flow is key to this incredible home which features ample timber and steel throughout its design.

Working with building company Prebuilt, Ramon and his business partner Simon Perkins design houses that are constructed offsite, many destined for bush or beach locations where good local trades are hard to find.
“If you’re building in the country, it can be a pain in the neck to assemble a good crew you can trust,” he says. “Whereas when you’re building offsite, you’ve got synergy with the same build crew coming through.”
The construction process of Ramon and Simon’s homes is not that different to traditional building methods, says Ramon, just truncated because the builder isn’t reliant on the weather or obliged to complete their projects in the standard order. For instance, a kitchen can be installed before the roof when it’s being constructed in a factory.

But beyond that, it’s pretty much business as usual. And that’s how it has to be, because otherwise you’re getting special trades in to do all sorts of things and the cost just becomes silly.”
The key to their ongoing success, says Ramon, is the relationship he has developed with Prebuilt. “I haven’t come across a similar sort of working relationship,” he explains. “I think people get a lot of comfort from the fact that they can have a look at Prebuilt’s website, or our website, and can see that we have both been around for some time. I think that actually gives them and us even greater credibility.”
Ecokit is another company that works in this space, supplying house kits to new homeowners, who then work with builders to construct their new home onsite. The director, Camilla Novotna, was inspired by her own search for a company to build her a house. She only wanted to use healthy building materials and couldn’t find the right kit home for her needs.

Ecokit has various kits to choose from, based on a modular system. “They start from 40 square metres, which is the smallest studio we do,” says Camilla. “We can design whatever you need, up to four bedrooms, combining the modules to get whatever you want.” And there’s no rush to lock in the number of bedrooms because you can add modules as your family grows.
While relatively new to the market, Ecokit has already completed six projects and is working on a resort of 20-plus units. Camilla feels that consumers are ready for change, especially when it comes to sustainable building practices.

It’s not just the process of building that’s important – it’s the whole life cycle of the house.”

Modular building, prefabricated home design and kit homes: what are the differences, the pros and cons and which one is best for you?
When it comes to building your new home, you’ll be faced with a myriad of different choices – some of the exciting ones include floor plans and colour schemes. But an important decision that needs to be made right at the start of your journey is the type of new home you’d like to build and the associated construction process. Think: traditional construction or prefab construction – which includes modular and kit homes, too.
While the process of traditional building is relatively well-known – all the action typically happens on-site with your home being built from the ground up – there is often little known about the scope and process of prefab construction.
You might be wondering what the differences are between prefab, modular, and traditionally built homes, or be curious about the pros and cons and costs associated with each build type.
You’ve got questions and we’re here to answer them.
In this article, we’ll explore the definitions and differences of modular, prefab, and kit homes and answer common questions such as:
In the traditional residential construction process, houses are built on-site from foundations to finishes and fittings. Within the traditional construction industry, there are many different types of builders from volume builds to custom homes – all of which are often referred to as ‘stick-built homes’ thanks to the frames that make up the structures.
Prefab construction methods offer an alternative to traditional residential construction where homes are built off-site in panels or modules which are then transported to the site to be put together and connected to services.
So outside of the construction methods, what are the differences between prefab and traditional construction? Generally, you can expect a prefab home to be constructed in less time and generate less waste in the construction process than the equivalent home design built by traditional construction methods.

Manufactured home construction isn’t new. History has shown prefabricated construction methods recorded as early 43 AD –even the Eiffel Tower was built by prefab construction methods.
However, it’s only in recent years that the industry has experienced a surge in popularity thanks to the streamlined construction processes with some substantial efficiency gains and environmental benefits.
So what exactly is a prefab home? And what are the benefits and costs associated with the prefab construction process?
What is a prefab home?
Prefab homes refers to homes that are built by the prefab construction process – which are built off-site in panels, components or modules for assembly and connection to services on-site. Because the term ‘prefab homes’ refers to the type of construction, there’s not one single style of prefab home. In fact, modular and kit homes are considered prefab homes.
As the styles of prefab homes can vary, so do the costs associated with building the home. According to data from HiPages, a basic prefab home (think: kit home) typically costs between $2500 to $3000 per square metre with the cost increasing for more high quality homes with premium cladding, luxurious interior finishes and additional features. It’s worth chatting to your prefab home supplier as there may also be additional costs associated with surveying and preparing the site, town planning and permits, construction and services connections.
Thanks to the construction process occurring off-site in one location, there are significant time savings in the prefab process that just aren’t possible in the traditional construction process. This includes tradespeople attending one site – rather than spending time driving around to multiple sites – materials being delivered in bulk to one site, and in some cases protection from the weather (which results in fewer days where tradies are rained off or heated off).
These time savings translate to cost savings which make the prefab construction process both quicker and more cost-effective than traditional construction methods.
That said, the type of prefab home you choose to build will influence the build timeline and the associated investment – we’ll cover that in more detail in the coming sections.

Time and cost savings aren’t the only benefits of prefab homes. As there is typically less material wastage associated with prefab construction, this building method is also better for the environment.
Prefab homes are also a great option for those seeking to build a new home in a remote or rural area – where there are often fewer tradespeople and associated businesses (such as materials and hardware stores). Like this Ecoliv home in Jindabyne – a remote location with little access to skilled construction people or services.

While kit homes fall into the prefab homes family, in that their trusses and components are constructed off-site, they’re often delivered to the site in pieces for assembly on-site by the owner or a builder engaged by the owner. In this section, we’ll explore what exactly makes a kit home and the associated pros and cons of this type of home.
As the name suggests, the core components of kit homes are built off-site, often in a prefab construction facility, and delivered to the site in a ‘kit’ for assembly and connection to services.
While kit homes can include family-sized residential homes, they’re often used to create ancillary dwellings such as granny flats and studios situated on the same land as the main property – usually a family home.
When it comes to building a kit home, there are generally three different stages of build that can be selected: lock-up stage home kits, lining stage home kits and final stage home kits.
As with prefab construction, on the whole, kit homes offer significant time and cost savings thanks to the nature of their design and building process. However, these efficiencies come from the cookie-cutter nature of the building design and construction process. Put simply, if you decide to build a kit home you’ll be choosing from a set range of designs with little ability to make adjustments.
The cost of kit homes can vary greatly depending on the type of kit home, the size of the home and the stage of build to which the kit is completed – lock up, lining, and final. For example, an 85 m2, two bedroom, one bathroom kit home may cost around $114,000 – around $1,300 per square metre – on par with the average cost of a home which is $1,393.55 per square metre according to the Australian Bureau of Statistics (ABS).
While there are certainly some cheap kit homes out there, on average the costs are similar to building a conventional home. In fact, according to data from Build Search the average cost to build a basic new home in Melbourne is around $1,390 per square metre however this soars to nearly $3,000 per square metre for homes with more premium finishes.
If you’ve been Googling ‘are kit homes any good?’, you might have come across a plethora of resources (and opinions) relating to the features and benefits. Ultimately, what makes a home ‘good’ depends on the needs of the occupants.
In the case of kit homes, if it’s speed and affordability there are certainly kit homes that will meet those criteria. However, the management of the build process will be almost entirely your responsibility as once the kit is delivered, it’s over to you to organise assembly and connection to services.
Like kit homes, modular homes are homes built by the prefab construction process. However, there is one major difference: modular homes are built to completion in volumetric modules which are then transported to the site to be connected to services – unlike kit homes, which are transported in pieces (as a kit) and assembled on-site. In this section, we’ll explain what defines a modular home along with its advantages, answering top questions and considerations.
A modular home is made up of sections (also known as volumetric modules) that are constructed off-site in a prefab construction facility. At Ecoliv, our modular homes are built in our facility located at The Gurdies on Victoria’s Bass Coast.
Each module is designed to either make up an entire small dwelling (like our EcoHut one-bedroom cabins) or combine with other modules to create a larger home (like our EcoLiving and EcoGeneration homes).
Ecoliv modular homes are made up of volumetric modules which are precision-designed to fit on the back of a truck according to weight requirements and/or for being craned onto site.
As a general rule, a new home built by traditional construction methods typically takes 12–16 months to build with the exception of homes built from pre-designed plans taking around six months.
While the build timeline for modular homes can vary depending on the size and complexity of the design, as modular homes are built in the prefab construction method, they are generally much more efficient to build than conventionally constructed homes.
At Ecoliv, the average build timeline for our modular homes is 20 weeks from the commencement of the construction process and installation occurs on site over just 1 day.
When it comes to the cost of modular homes, a few things need to be considered – particularly if you’re choosing a sustainable modular home.
The slope and orientation of the site impact the design of the home and the level of complexity of the construction process which will have a bearing on the cost of the modular home. Equally important is considering the distance that the modular home will be transported as this influences the cost as well. While these factors influence kit homes as well, it’s especially important to consider when planning a modular home – which is built to specification entirely offsite.
Then there is the construction cost which is going to be influenced by the square meterage of the home along with the build quality, material selection, finishes and any customisations. As a guide, Ecoliv has a selection of pre-designed modular home floor plans to choose from ranging from studios to four-bedroom family homes. Our EcoHut range (which comprises one and two-bedroom configurations) starts at $228,000 and our luxurious and operationally carbon-neutral EcoGeneration range (which offers up to four bedrooms, two living areas and 2.5 bathrooms) from $656,000.
Fast build and installation turnaround aren’t the only advantages of modular home building.
The efficiency gains from building in a controlled facility include: twinning production where similar structures are built at the same time, tools and materials are close at hand and the build site can be prepared simultaneously while the home is constructed off-site.
There are also numerous environmental benefits of modular construction. Improved building quality and more air tight structure are achieved by building the home in a controlled construction environment. Modular construction also vastly minimises the amount of on-site waste and land disturbance.
One of the key features (and benefits) of modular homes is the ability to transport them from the construction facility to your site. While the cost of transporting your modular home can vary depending on the distance of travel required and the size of the modules, it’s usually around $1,000 per truck per hour.
Where the site is in a remote or rural location, there may also be additional costs to accommodate trades for the duration of the delivery. And for urban settings, there are sometimes costs associated with local council and transport authorities to close roads and allow for cranes to operate over occupied dwellings.
While we might be a tad biased, we believe Ecoliv modular homes are a wise investment. And not just financially. All our homes are designed to maximise the comfort and wellbeing of occupants with passive solar design, cross-flow ventilation and low VOC paints and cabinetry contributing to the health of the home.
With a 7 star energy rating (compared to the 6 star industry standard) and a sustainable design and building process, solar energy and a 10,000 litre tank included, Ecoliv homes aren’t just a good investment in your health and wellbeing, they’re an investment in the future of the natural environment too.
Plus with the associated operational cost savings that can be made by reducing reliance on mains gas, electricity and water, there are some major environmental (and economic) perks too.
If you liked the sound of the faster build time frames, improved environmental outcomes, and healthier living for occupants that come with Ecoliv sustainable modular homes, then we’d love to help you find the right design for you – or work with you to bring your custom home vision to life.
