CTBUH recognizes 1 Bligh as one the world's 50 most influential buildings

The prestigious Council on Tall Buildings and Urban Habitat (CTBUH) has elected our Australian project 1 Bligh Street as one of the most influential buildings of the last 50 years. The 139-metre tall 1 Bligh office building in Sydney was inaugurated in autumn 2011. Due to its compact geometry and a slight rotation in relation to its site, all offices enjoy unobstructed views of the city’s beautiful harbor. All the typical ground floor functions have been raised to allow for a public plaza at street level. The high-rise building is a highlight in Sydney’s skyline. In addition to its spatial efficiency, the building boasts an ecological concept that is not only unique for the city but also for the entire Australian continent. The building is the first high-rise tower to have received the highest six star certificate of the Australian Green Star environmental rating system. Its fully glazed tower is equipped with a double-skin façade and is ventilated by an atrium that rises up the building’s entire height.

The CTBUH was founded in 1969 by Lynn S. Breedle at Lehigh University as the “Joint Committee on Tall Buildings”. The organization has been headquartered in Chicago’s historic Monroe building since 2016. It is a non-profit organization, which collects, offers and distributes information on tall buildings. The CTBUH organizes research, publications, events, online resources and much more. The organization’s research department is particularly interested in the next generation of tall buildings and supports original research into the development of sustainability. It also offers a free database on tall buildings, which is updated on a daily basis.
