The NSW government has announced a dramatic new plan to redevelop an area over the rail lines at Sydney’s Central Station into a new high-density precinct that would bring thousands of extra workers and residents to the southern end of the CBD.

The masterplan for the 24ha site will include up to 15 new buildings that will range in height from four to 34 storeys, and house offices, hotels, apartments, restaurants and bars, and a variety of other community and cultural spaces.

The site will also have 60,000 sq m of open space in the form of three new parks, a major public square and several plazas.
