ONE FIFTY Collins blends elements of old and new Melbourne in a building with excellent sustainability credentials and provides a flexible and inspiring working environment for its tenants.

Located between Scots’ Church and The Assembly Hall on Melbourne’s most prestigious street, the building is a composite structure with reinforced concrete framing from basement level 3 to ground level and a steel-framed structure from ground level to roof level. Approximately 1300 tonnes of structural steel was used in the building, which preserves the heritage-listed façade of Melbourne’s first multi-deck car park built in 1938. Westpac Banking Corporation is the building’s anchor tenant and occupies levels 5–12.

Awarded Best Sustainable Building at the 2016 Victorian Master Builder Awards, ONE FIFTY Collins utilises underfloor air conditioning with complete tenant control. It also features a gas-fired cogeneration plant that generates its own power on-site using natural gas and water storage and re-use systems to maximise water savings.
