GPT is seeking to bring city fringe chic to Melbourne’s retail heartland with the 19,400-square-metre timber office tower it plans to build on top of the Melbourne Central mall at 300 Lonsdale Street. …“Frame will feature abundant natural light and a warehouse-style environment, with the design of the building aimed to improve the sense of well-being of its occupants,” GPT’s head of office and logistics Matthew Faddy said. …”Clearly part of the marketing pitch is that it’s a CLT building,” Mr Johnston said at the time. “Certain tenants will like that sort of space and be prepared to pay a bit more.” .
