Buildings in Collins Street, built as annexes to the Colonial Mutual Life Building, Wolfgang Sievers, 1959.

Melbourne literally went through the roof with the lifting of the 132-foot height restriction in 1955. As a result, many heritage buildings were demolished to make way for high-rise office blocks, radically changing Collins Street. Photographer Wolfgang Sievers was commissioned to comprehensively document numerous buildings prior to their demolition, including the Colonial Mutual Life Building. Though once considered the 'best proportioned building in the city', it was destroyed along with many other examples of fine architecture.
