A landmark mixed-use development overlooking the iconic Sydney Harbour

One Alfred Street, Circular Quay

One Circular Quay is a premium mixed-use development in a prime location at 1 Alfred Street, overlooking the iconic Sydney Harbour. This landmark development for the area would feature a 60-storey residential tower on its western end, alongside a 25-storey luxury hotel with public space at ground level. The towers would be connected by a 6-level basement car park.

Stantec's engineers were engaged to execute the mechanical, electrical, vertical transportation, environmentally sustainable design (ESD), and fire engineering services. We collaborated with the ESD team leader to target 5 Star Green Star ratings in Design and As Built categories. The tight core of the building proved challenging for the lift, but we introduced an alternative lift assignment to meet the building’s needs. Rather than using a set base point for the power used by the lifts, we analysed the actual power consumption and used this to build into the BASIX report—a NSW government planning requirement for building sustainability.

Without many residential buildings in the area, not only does this development add desirable living space to the district, but it also features incredible views of the opera house and Sydney bridge—unrivalled appeal.
