Sydney-based Treelight Development Group has submitted a development application for what would be Australia's second skinniest tower. Proposed for 466 Ann Street in Brisbane, the application cites a building width of only nine metres. The current thinnest building in the country, Melbourne's Phoenix Apartments, comes in at just 6.7 metres wide.

The building at 466 Ann would be quite a bit taller than the 28-storey record holder however. It would tower 37 storeys into the sky, hosting 66 residences. All of those units would hold two bedrooms, with the exception of a single four-bedroom penthouse. Considering its ultra-thin frame, the building would house a respectable number of amenities. A 315-square-metre commercial space at ground level acts as the main public convenience, while the rooftop communal pool, barbecue area, boardroom, and lounging area exclusively serve residents.

Designed by the award-winning team at ROTHELOWMAN, the curved form of the tower is highlighted by its spacious balconies. Renderings depict draping greenery on some portions of the building, which looks to be clad in a dark finish. A previous application for the site had sought approval for a 13-storey residential building.

With urban properties becoming more scarce and valuable, the trend of super-slim skyscrapers is taking hold around the world. Manhattan is already known for its crowded corridors of highrises, yet with the recent completion of 432 Park Avenue and the upcoming 111 West 57th Street, the height-to-width ratio on new projects is continually being stretched.
