1 Bligh Street, Sydney is the next generation in high performing sustainable office space, combining leading edge design, technology and sustainability in a premier location in the Sydney financial hub.

It is the first office tower in the Sydney CBD to achieve a 6 Star Green Star Office Design rating by the Green Building Council of Australia and was also awarded the 2011 Asia Pacific Property Award and the International Architecture Award.

The elliptical-shape floor plates and the column-free atrium offer large amounts of natural light and spectacular views to Sydney’s Harbour Bridge. SAS International’s ceilings feature within the environmentally acclaimed building.

A custom made metal ceiling was manufactured for the perimeter zones. The curved nature of the building created a design challenge and technical expertise was crucial to make the ceiling system work. SAS International Australia designed and manufactured a ceiling solution that combined perforated rectangular panels interspersed with 3.6-metre long, non-perforated trapezoidal panels for integrating services such as sprinklers. The perforated metal ceiling panels were installed to help achieve correct airflow from the chilled beams.
