FOLLOWING designs for a trio of towers in Brisbane and a pair of towers in Gold Coast, the London-based architect, Zaha Hadid has just submitted plans for another tower, this time in Melbourne, Australia. Like the Brisbane and Gold Coast towers, the proposed project, a 54-story mixed-use skyscraper, also employs a sculptural, tapered expression, creating more open space at the base. Despite the notion that Melbourne is reaching an oversupply of residential housing units, the tower will comprise 420 apartments, 118,000 square feet (11,000 square meters) of retail space, and 60,000 square feet (5,600 square meters) of commercial office space.
