In 1972 after three years of construction, BHPs new headquarters stood completed with 41 floors at 140 William Street, Melbourne showcasing BHPs prime product, steel.

Known at the time as BHP House and designed by Yuncken Freeman Architects, the expression of the structural skeleton both internally and externally (via steel cladding) met BHPs desire for a complex formation of steel to create a visually strong structure. At the time of completion, 140 William Street stood as the tallest building in Melbourne and the tallest steel framed building in the Southern Hemisphere. At 152m tall, column free core to facade, the building demonstrated the power and strength of BHPs product and was the first Outrigger & Belt Truss Building in the world – something that is now common practice for super tall buildings.

140 William Street is included on the Victorian Heritage Register for its significance to Architecture, History and Technology (its innovative structural application of steel and concrete, leading to open floor plates).
