About 181 William Street

181 William Street is a new major corporate presence in the high ground of the west end commercial precinct of Melbourne. The entire project is designed on a holistic basis to integrate the façade with all services systems to achieve high quality environmental performance. During the course of a comprehensive design process, all services systems were integrated to ensure high quality environmental performance, flexibility and long life.

The tower façade is visually arresting in the use of colors in the vision and spandrel glass, creating a balanced geometric pattern that captures a sense of movement across the façade. The russet color pallet was selected to reflect a richer and more distinct corporate presence. The range of seven colors to the spandrel and vision glass has been distributed in an ordered manner that has been inspired by the dot painting technique of Australian indigenous art. The white columns are metal clad with the lower sections expressed in polished stone. The elevated podium is clad in zinc with expressed joints and flush glazing to match. The north and south inset façades are in clear flush glazing.

The tower is designed to achieve maximum natural light, views and workplace flexibility. The project has achieved a certification rating of Five Green Stars and 4.5 Star ABGR. These rating systems are administered by the Green Building Council of Australia and subject to rigorous audit and monitoring. These assessments cover all elements of sustainable performance, including the consideration of embodied energy, recycled construction materials, indoor air quality and VOC analysis, and ongoing environmental performance. This is equivalent to a LEED Gold rating.
