161 Castlereagh Street

Commercial tower with a 6 Star Green Star Rating

161 Castlereagh Street, also known as the ANZ Tower, is a 43-storey office tower boasting panoramic views over the Sydney Harbour and Hyde Park. The building offers modern, open-plan workspace for employees to interact and collaborate, as well as a range of customers suites. 

Facilities include:

  • Retail and dining precinct at lower ground
  • Public open spaces
  • Pedestrian laneway connecting Castlereagh Street and Pitt Street

The building design applies new technologies to deliver operational and environmental benefits including the use of solar panels, light sensors and extensive LED lighting. A tri-generational power system is used to lower the carbon footprint and additional sustainable materials have been used throughout the fit-out, such as the use of carpeting from recycled material. 

The ANZ Tower was awarded a 6-Star Green Star – As Built Office Design v2 from the Green Building Council of Australia, which makes it one of the largest office buildings in Sydney to be awarded this prestigious award.
