When 25 Martin Place (previously the MLC Centre) was unveiled in 1978, it was unlike anything Australia had ever seen. A modernist vision of stark white concrete, granite and glass, it transformed the Sydney skyline, leaving a legacy that stands today.In the words of architect Harry Seidler, the vision in the 1970's was to create a 'city within a city'. Now with a $170 million investment, this living landmark is being transformed into a vibrant new destination for future generations to enjoy. Today, 25 Martin Place is the centrepiece of Sydney, where workers and visitors embrace business, fashion, dining and culture.
