Cloud-shaped hotel among designs for Australia’s tallest building

The ‘Urban Tree’ design by Mad Architects and Elenberg Fraser will feature a public level that looks like a cloud, with 360-degree views of the city. Pictures: Beulah.

An illuminated cloud-shaped hotel, gardens on the roof of a skyscraper and a tower designed to look like a propeller are among the shortlisted designs for a $2 billion skyscraper at Southbank in Melbourne.

The tower is expected to be Australia’s tallest building, with five of the six shortlisted architects producing designs that soar beyond the 322.5m Q1 tower in Queensland.

The building is to be constructed by developer Beulah on a site currently occupied by a BMW dealership, which was sold last year in a deal worth more than $100 million.
