Originally built in 1938 for the New South Wales Department of Motor Transport, and known as Transport House, this classic art deco building has undergone a complete A$30 million refurbishment by Mulpha Australia and is now one of Sydney’s most prestigious business addresses.

The building’s myriad historic features have been retained and restored while a range of state-of-the-art services, including ‘chilled beam’ air-conditioning, raised access flooring for power reticulation and double glazing of the original windows have been designed to provide 4.5 star ABGR energy efficiency and modern office utility.

Mulpha acquired the historic building in 2002 as part of its acquisition of another of Mulpha’s major assets, the adjacent InterContinental Sydney, and has worked closely over the years with the Heritage Council on the painstaking rebirth of what is one of Australia’s most significant historic buildings.

The restored common areas include a marble staircase and banisters, original escalator, wood panelled boardroom and hallways, as well as twin street frontages to both Macquarie and Phillip Streets.

The building opened for business in July 2009 after remaining largely unused for close to 35 years.

In July 2010, 99 Macquarie Street was named Winner - Heritage Preservation in the prestigious 2010 Urban Taskforce Australia Development Excellence Awards.

Urban Taskforce Chairman of Judges' Panel, Chris Johnson, stated that "the project demonstrates how a heritage building can be refurbished to attract top tenants and provide exceptional environmental outcomes".

99 Macquarie Street is home to Mulpha Australia Limited (from May 2010) and other tenants are M&C Saatchi and the JB Fairfax-related Cambooya and Marinya Media entities.
