Build a home that suits your block, your lifestyle, and Victoria’s changing weather, without the long timelines of a traditional build. Outback Building Group designs and manufactures modular homes that are delivered to site and installed with a streamlined process, whether you’re in Melbourne, regional Victoria, or coastal areas.
Modular homes work for a lot of real-life scenarios. Popular builds across Victoria include
for family, adult kids, or independent living on the same property
to create extra space without extending your main home
that stay separate from the day-to-day noise inside the house
for visiting family or short-stay use
where you want comfort, but a simpler build process
Need a functional space that can be delivered and installed with less disruption to your operations? We design modular buildings for businesses and organisations across Victoria, including:
If you’re not sure whether your use case fits, tell us what you need, and we’ll advise on the best configuration.
A comfortable home starts with smart design choices. Our modular homes can be specified with features that support energy efficiency and reduce ongoing running costs.
Because your home is built in a controlled environment, materials are handled more efficiently, and waste is reduced. It also means weather delays are less likely to stall construction progress.
You’re not choosing a one-size-fits-all box. We tailor layouts, inclusions, and finishes based on how you want to live and what your site allows.
Modular homes are a type of prefabricated home. The main difference is that modular builds are manufactured in sections in a factory, then delivered and installed on site. People also use terms like prefab building or prefab building systems. The key point is that most of the build happens off-site, then the home is finished and connected on your property.
Your building journey typically follows this structure: initial consult and home design, site assessment, required documentation and approvals, manufacturing, then delivery and installation. After that, final checks, utility connections, and finishing work are completed, so the home is ready for modern living.
Site preparation depends on your block, access, slope, and local requirements. Site costs can be influenced by soil tests, access for delivery, drainage needs, service proximity, and the type of foundations required. We’ll talk you through what’s likely for your site before you commit to anything.
Yes, modular homes still have foundation requirements. Depending on your site and design, this may involve stumps, piers, or a slab. While most of the home is factory-built, there is still important on-site construction, including foundations, installation, joining modules (if applicable), and final services.
Many parts of the build can be scoped clearly upfront, which helps with visibility around fixed costs. That said, every project can still have variable items like site works, approvals, finishing costs, and utility connections. We’ll outline what’s included and what sits outside the core build so there are fewer surprises.
We use reliable building materials suited to Australian conditions and project requirements. Because much of the build happens in a controlled environment, we can maintain stronger quality assurance checks during manufacture, then complete final inspections after installation.
Modular does not mean basic. With the right home design, layout planning, and finish selections, modular homes can feel like a true dream home. This is where thoughtful planning and smart Modular Architecture choices make a real difference, especially on smaller blocks or tighter sites.
Yes. We can design sustainable homes by prioritising insulation, glazing, ventilation, and energy-ready planning. A sustainable home is usually less about one feature and more about the full design working together to improve comfort and reduce ongoing energy use.
Yes. We deliver commercial projects across Victoria, including offices, amenities blocks, classrooms, change rooms, and other modular spaces. The same principles apply: clear scope, efficient build timelines, and reliable quality control.
Often, yes. Because the bulk of the build is completed off-site, there’s typically less extended trade traffic and fewer weather-related delays during the on-site phase. Your property still needs site works and installation time, but the on-site timeline is usually more contained than a fully traditional build.
Start with a brief on what you want the space to do, then we’ll confirm feasibility around access, layout, and site constraints. From there, we can advise on likely site requirements, next steps in the building process, and what information we’ll need to prepare a quote.
If you’re considering a modular home, we’ll help you work through the practical details first, including site access, intended use, preferred layout, and finish level. From there, we can provide next steps and a tailored quote.
