Introducing the Patented REZICAST® Home Building System
Developed by Mick Johnson, a builder with over 20 years of experience, the Patented REZICAST® Home Building System is a construction method designed to streamline the residential building process. With a focus on speed, efficiency, and resilience, the system enables builders to achieve:
- Lock-up in as little as 10 days
- Full completion in as little as 10 weeks
- Reduced labour and trade waste
- Minimal defects and ongoing maintenance
- Cleaner, safer sites
Unlike traditional methods, REZICAST® uses factory-made precast panels that arrive straight and true, ensuring defect-free installation and long-term durability. The system is engineered to perform on almost any terrain, and application, being recognized for its strength, acoustic and energy efficiencies, saving homeowners on heating and cooling costs for years to come.
Proven Success in the Field
One standout project includes a 5-bedroom home built by Winsman Group in partnership with the Aboriginal Housing Office (NSW Government). Completed in just 13 weeks, this project showcases the speed and reliability of the REZICAST® system.
“Adopting the REZICAST® System for an Aboriginal Housing Office project significantly accelerated the speed at which the construction was completed. The intelligent design of the REZICAST® System enabled us to achieve true lock-up in less than 10 days, minimizing our exposure to weather conditions. The versatility of the system is a great advantage, particularly during the wetter seasons.
We were able to become cashflow positive within the early weeks of the project. As the solid precast concrete panels are manufactured in factory conditions, it ensures a high-level quality product. This mitigates workmanship errors and defects requiring rework.
In comparison to a conventional build, we found that using REZICAST® System, there was far less waste on site, and we were able to save dramatically on preliminaries. As a result, handover can be achieved within a few months as opposed to 6–12 months.
The underlying benefit for our business is not just the efficiencies for onsite resources dedicated to the project, but the office resources allocated to the project. It gave us more room to focus on other projects and free up our business’s resources.
We found that due to the speed at which construction activities transition, we had to be proactive in planning. Feedback was positive from our subcontractors, as the program was precise, and they were able to work off a firm program.
Overall, we were impressed by the REZICAST® System’s adaptability to strict design briefs, to meet government specifications, and varied site constraints.
We believe the Patented REZICAST® Home Building System is poised to become a new construction standard in Australia, helping to address the housing shortage while delivering efficiencies on future projects well beyond residential builds.”
— Sam Manoun, Director, Winsman Group
Award-Winning Innovation
REZICAST®’s most recent recognition is with an industry award for Modular and Prefabricated Housing, presented by the Housing Industry Association (HIA).
This award validates years of hard work, investment, and innovation, and positions the patented REZICAST® Home Building System as a credible and forward-thinking solution for the future of housing in Australia.
“At REZICAST®, we have a genuine desire to make a difference.”
— Mick Johnson, Managing Director
