In 2012, these plans were revised and resubmitted in favour of mixed–use residential and hotel skyscraper, reaching 388 metres (1,273 feet) and comprising 108 levels.

[6] The site was purchased by architecture firm Fender Katsalidis Architects in April 2008, for A$14.2 million, after the original tenancies ran an expression of interest campaign.

[7] In 2009, plans were submitted by Fender Katsalidis Architects to the City of Melbourne for an A$400 million residential building to be built on the 70 Southbank Boulevard site.

In its original proposal, the building, 70 Southbank Boulevard,[8] was planned to be 226 metres (741 feet) in height and consist of 532 residential apartments, six levels of office space, a fresh food market and other retail amenities, spanning 72 floors.

[12] Nonetheless, in July 2012, the site was put up for sale through an international public expression of interest campaign and was listed at A$25 million.

[9][13] In November 2012, Katsalidis revealed revised plans for the building which would have seen it "super-sized" to 388 metres (1,273 feet) in height, with 108 floors.

The new proposal integrated the previous plans, but went on to include more residential apartments, a six-star hotel, and a two-storey star-shaped sky lobby with restaurants and bars.

[18] A prominent component of this proposal was its star-shaped sky lobby on the 83rd and 84th floors, which would have protruded 9 metres (30 feet) outside of the building, in similar vein to the Eureka Tower's Edge experience, only larger.

[18] Fender Katsalidis Architects incorporated the Chinese system of geomancy, known as Feng shui, when developing the new proposal.

[24] Despite concerns, the project received its final approval on 18 March 2013 by Guy, who went on to describe the development as "a magnificent addition to Melbourne's skyline.

[34] At the time, it was claimed that the tower would have extended 13 metres (43 feet) into Essendon Airport's flight path "envelope," whose southerly approach requires a 373-metre (1,224 ft) height limit to any potential obstruction within 15 kilometres (9.3 miles) of the airfield.

[34] When asked about this situation, architect Nonda Katsilidis claimed that the flight paths would not be a problem, and that a technical solution could be drawn up if required.

[38] The star-shaped sky lobby feature from the previous proposal was incorporated in the design of the building, albeit with various purposes (as opposed to a public observation), and would be located on levels 69 through to 71.
