A landmark in the Adelaide CBD, this development seamlessly integrated the old with the new, delivering a modern, sustainable and amenity-rich office building while preserving the State heritage listed façade of this historic site.

This included the demolition of an existing building and the construction of 14 levels of PCA A-grade commercial office space along with integrated fitouts for anchor tenants Service Australia,Telstra and NAB. In addition to the 40,000sqm of office space, the two-level basement comprises end of trip facilities, amenities and carparks with the ground level including 3,600sqm of retail tenancies and public retail spaces, and a commercial lobby. The roof level contains plant space and a roof terrace.

The site is tightly bordered by businesses on James Place, Clarence Place and Imperial Place, requiring regular stakeholder communication and liaison.

Designed by globally recognised Cox Architecture, the careful retention and restoration of the State heritage listed Sands and MacDougall façade was a key requirement of successful delivery. This included the use of structural steel framing to brace the building back to the temporary structure as well as underpinning the foundations to ensure the building was temporarily restrained throughout the in-ground construction works until the connecting outrigger walls were formed up as part of the permanent solution.

Sustainability is at the core of the development, meeting the requirements for industry leading standards, including a 6 Star Green Star and As Built v1.2 certification, 5 Star NABERS Energy Commitment Agreement and WELL Core Platinum certification, and the base building is net zero emissions in operation.

The building was carefully designed to utilise natural light and state-of-the-art air purification systems to support the health and wellbeing of tenants, which has supported the building’s 6 Star NABERS Indoor Environment rating.
