The refurbishment of 83 Proprietary St is a model of cost-effective and sustainable design, reusing over 80% of the existing structure from 1986. By raising the building by 1.5 meters using hydraulic jacks, the project successfully added 27% more space without the need for a complete rebuild, significantly reducing costs. Key sustainable upgrades included the installation of new roof insulation, Trimdek cladding with insulation, and energy-efficient LED lighting, all contributing to the building’s improved energy efficiency.

Interior enhancements were also a priority, with new bathrooms installed and the original concrete floors refurbished, maintaining the building’s structural integrity while modernising its functionality. The project reused the existing structural steel, which was coated to ensure longevity, further emphasising its commitment to sustainability. The front facade received a modern update with the use of concrete tilt panels and high-efficiency glass, improving both aesthetics and energy performance.

Overall, the refurbishment at 83 Proprietary St demonstrates how thoughtful design and material reuse can lead to a successful and sustainable upgrade, enhancing the building’s functionality while minimising environmental impact and costs.
