Unions ban workers from demolishing Sydney's brutalist Sirius building
Australian trade unions have banned workers from demolishing one of Sydney's only brutalist buildings, which failed in its bid for heritage listing.

The Sirius public housing block was designed by architect Tao Gofers in the 1970s. It has 79 apartments as well as communal areas including a lounge, library and roof terrace.

Each residence is housed within a concrete cube, with large windows giving residents unparalleled views of the Sydney Opera House and Harbour Bridge.

The proposed redevelopment of the Sirus apartment block is part of a wider sell-off of public housing throughout the nearby Millers Point neighbourhood. Plans for the site include 250 new luxury apartments.
