Adaptive Reuse

The adaptive reuse redevelopment of a 50-year-old structure involved stripping the building back to its concrete frame and adding an extension to the south - the building was reclad with our Thermosash PW1000 Unitised High Performance Curtainwall, delivering energy efficiency as well as clear views across the harbour.

Installation

The façade works were delivered across three key phases: Podium, Tower, and Level 21, each with its own coordination requirements. Despite broader project pressures, Thermosash consistently completed its scope within the required programme timeframes by staying proactive, responsive, and solution-focused.

Tower: The tower phase formed the largest portion of the façade package. The curtainwall ran consistently ahead of programme, which allowed the builder to advance the critical internal fitout faster than would otherwise have been possible. On the lower levels, a rear-glazed system was incorporated to achieve the mullion projections the architect sought, and LED lighting was integrated throughout the façade.

Rooftop: Thermosash worked closely with the architect to deliver a high-end, complex rooftop bar finish for the end user. This included numerous skylights, canopies, balustrades, large-format sliding doors, cladding, and lintel glazing to the south side.

Podium: Thermosash provided the glazing, revolving door, glazed canopies, and cladding to the podium entranceway, tying in seamlessly to the curtainwall above.

Throughout the project, Thermosash remained committed to supporting the wider team, maintaining momentum and expediting processes where required to deliver a successful outcome.
