The refurbishment project at 83 Proprietary St exemplifies a sustainable and cost-effective approach to modernising existing structures. By reusing over 80% of the building’s original 1986 structure, the project significantly reduced costs compared to a complete rebuild. A key innovation was the use of hydraulic jacks to raise the building by 1.5 meters, which effectively added 27% more space, maximising the utility of the existing footprint.

Sustainable upgrades were a cornerstone of the project. New roof insulation and Trimdek cladding with insulation were installed to enhance energy efficiency, complemented by energy-efficient LED lighting throughout the building. Interior improvements included the installation of new bathrooms and the refurbishment of the existing concrete floors, preserving the building’s core elements while modernising its functionality.

The project also focused on extending the building’s lifespan by reusing and coating the structural steel for added durability. The front facade was modernised with the addition of concrete tilt panels and high-efficiency glass, improving both the building’s aesthetics and its energy performance. Overall, the project is a testament to the benefits of sustainability, material recycling, and thoughtful design, delivering a functional, modern space that respects its original structure while meeting contemporary needs.
