At Modular Buildings Australia, we are committed to using high-quality, Australian-made materials to ensure durability, compliance, and long-term performance. Our structures are built using BlueScope Steel, a globally recognized leader in steel manufacturing, ensuring that every frame meets the highest structural integrity standards.
We source our roll-formed components from Stramit, one of Australia’s most trusted steel manufacturers, guaranteeing precision-engineered components that align with industry best practices. For roofing and wall cladding, we exclusively use Colorbond® steel, known for its advanced corrosion resistance, thermal efficiency, and longevity in Australia’s harsh climate.
By choosing Australian-made materials, we maintain strict quality control, support local manufacturing, and ensure that our products meet or exceed Australian building standards. This commitment reinforces the reliability, strength, and sustainability of every structure we design.
At Modular Buildings Australia, we prioritize structural integrity and compliance in all our projects. To ensure the highest standards, we collaborate with esteemed engineering firms:
Northern Consulting Engineers (NCE): Based in Queensland, NCE is a prominent structural and civil consultancy with operations extending nationwide and into New Zealand. Their team comprises registered professional engineers and a diligent drafting team, delivering high-quality, innovative, and cost-effective solutions across residential, commercial, and industrial sectors. NCE's commitment to exceeding client expectations aligns with our dedication to excellence.
John Towler Engineering (JLT): With over 30 years of experience, John Towler is a seasoned structural and civil engineer based in Gympie. Specializing in custom tasks, including shed homes, JLT brings extensive knowledge and expertise to our more bespoke projects, ensuring tailored solutions that meet specific client requirements.
Our collaboration with these reputable firms guarantees that every structure we deliver is engineered for safety, durability, and compliance with Australian standards.
At Modular Buildings Australia, we exclusively use Colorbond® steel for our roofing and wall cladding to ensure the highest level of durability, performance, and aesthetic appeal. Manufactured by BlueScope Steel, Colorbond® is engineered specifically for Australia’s demanding climate, offering exceptional resistance to corrosion, thermal efficiency, and long-term structural integrity.
Each sheet of Colorbond® steel undergoes rigorous testing to withstand extreme weather conditions, including intense UV exposure, heavy rainfall, and coastal environments. The advanced Activate® technology incorporated into its composition enhances its protective layers, extending lifespan and reducing maintenance.
Colorbond® also offers a wide range of color options, allowing our clients to customize their structures while benefiting from a material known for its low maintenance, fire resistance, and thermal efficiency. Every Colorbond® product we use is backed by BlueScope’s warranty, ensuring peace of mind for years to come.
By choosing genuine Colorbond® steel, we reinforce our commitment to strength, sustainability, and superior quality in every build.
At Modular Buildings Australia, we utilize Stramit’s extensive distribution network to deliver our products efficiently across most of Australia. With Stramit locations in every state except the Northern Territory, we can ensure that our shed and shed home kits are transported using their well-established logistics system.
While our standard delivery service covers the majority of locations, there are rare cases where direct site delivery may not be feasible due to access limitations, remoteness, or logistical constraints. In such instances, we work closely with Stramit and alternative transport providers to explore the best possible delivery solution.
Typically, delivery is included in your quote, ensuring transparency and predictability in cost. Our goal is to make the process as seamless as possible, leveraging Stramit’s national presence to maintain efficiency and reliability in every shipment.
If you have specific site considerations or require clarification on delivery feasibility, our team is always available to assist in finding the best logistics solution for your project.
Our Difference
What makes us different.
At Modular Buildings Australia, we are among the top 1% in the industry when it comes to accuracy, precision, and execution in 3D modeling and take-offs. Our expertise in Building Information Modelling (BIM) allows us to break down complex, custom projects with unmatched efficiency—transforming intricate designs into practical, buildable solutions.
Unlike many competitors who rely on conventional 2D drafting with higher margins for error, our BIM-driven approach ensures:
- Highly accurate material take-offs that eliminate waste and miscalculations.
- Seamless project execution by identifying and resolving potential issues before they arise.
- Reduced costs and risk, delivering greater value and certainty to both individual customers and large-scale businesses.
By leveraging BIM at an advanced level, we de-risk investments for our clients, ensuring every structure is engineered to work the first time, every time. This precision allows us to reduce unnecessary overheads, streamline construction processes, and offer superior, cost-effective solutions without compromising quality.
At Modular Buildings Australia, we don’t just compete—we lead.
