60 King William Street, located on Adelaide’s premier commercial address, is Adelaide’s largest commercial real estate project. The building consists of 40,000 square metres of A-Grade office space and 3,600 square metres of retail space to house 3,500 commercial and retail workers. The 14-story office tower includes a single level basement. 60 King William Street has been designed with industry-leading environmental sustainability top of mind with 6 Star Green Star, 5 Star NABERS Energy ratings, 6 Star NABERS Waste rating and Gold Well certification.

The building houses Adelaide’s first sky lobby providing a premium entry experience for the skyrise tenants and an exclusive roof-top terrace. A State-of-the-Art a centralised business hub, touchless access, facial recognition and WiredScore certification are part of the building.

The retail areas will provide a variety of food and beverage options including a supermarket.

The design of the building needed to accommodate the retention of the heritage Sands and McDougall Façade. The Sands and McDougall building had undergone several renovations in the late nineteenth century and, in 1933, the Art Deco Façade was one of them. The design had significant influence and contribution to South Australian Architecture and was considered essential to be incorporated in the new building.

Added Value

RBG was actively involved in the project from the earliest stages of the development. We were subsequently novated to Built and entrusted with the design of various temporary works elements including the retention of the heritage listed Sands and MacDougal façade.

Our responsibilities encompassed the design of essential load-bearing components such as vertical and lateral elements, the basement, roof, and pile caps. Furthermore, we played a pivotal role in establishing the framework for the design of post-tensioned floors and piling.
