One Barangaroo becomes Sydney's tallest building

The topping out of WilkinsonEyre’s Crown Sydney (also known as One Barangaroo) was celebrated by client Crown Resorts last week, the 275m high hotel, resort and residences becoming Sydney’s tallest building.

After four years of construction, Crown Sydney will open its 349-room hotel in December 2020, alongside 14 restaurants and bars, along with retail.  Homeowners at Crown Residences at One Barangaroo, located in the upper floors of the building, are on schedule to move into the building in the first half of 2021.

The building was primarily designed in WilkinsonEyre’s London office with architects based on site at critical stages, and the practice has now set up a satellite office in Sydney to accommodate new work.  The interiors are by New York based Meyer Davis.

Speaking about the scheme, Chris Wilkinson said “The building is conceived as an inhabited sculpture made of 3 petals that twist as the rise up together. The sculptural form has pushed known technology almost to the limits, with helical perimeter columns in concrete, complex glazing systems to deal with the changing curved forms and the marble tracery around the podium.”

Unique construction challenges include the installation of 10,000 glass panels, of which 80 per cent needed to be sized individually. To date, 237,888 tonnes of concrete and approximately 20,000 tonnes of steel have been needed to complete the structure. 

The project was won in international competition in 2013.  The Barangaroo site on Darling Harbour is already home to International Towers by Rogers Stirk Harbour while the adjacent One Sydney Harbour by Renzo Piano building Workshop is now on site.
