About 171 Collins Street

Developed directly out of the richness of its inner city location, 171 Collins Street is the Australian province of Victoria’s first Premium Grade 6-star Green Star office building in more than 20 years. The crystalline tower provides an iconic focal point to Melbourne’s city skyline, featuring an impressive nine-story internal glass atrium, premium finishes and facilities, efficient side core floors, a woven crystalline facade and the latest in technology and environmental design.

Its design has four main components: the Mayfair Building, the Flinders Lane podium, the atrium and office tower; together, these form a unified whole. The Collins streetscape is maintained by setting the tower form back 32 meters from the street, while the Flinders Lane facades emulate the textures and scaling devices of the surrounding brick warehouse buildings. The new 171 Collins Street complex lends an elegant but not overpowering backdrop to the historic Mayfair Building, whose façade continues to enclose the Collins Street entrance to the project.
