One Central Park, Residential complex in Chippendale, Australia

One Central Park is a mixed-use dual skyscraper in Chippendale, Sydney, with an east tower of 34 floors and 117 m and a west tower of 12 floors and 64.5 m, joined above a six-level retail base. The facades carry horizontal balconies and glass panels planted with vertical gardens, and a cantilevered heliostat projects from the taller tower. A circular sign reading "Central" sits at the centre of the lower facade.

The site housed Carlton & United Breweries until Frasers Property bought it for $208 million in 2007. The NSW state government approved the enlarged Central Park master plan in 2009, and construction of the park, roads and basements began in February 2010. Apartments in the west tower were completed in May 2013, and the building officially opened in December 2013.

The vertical gardens were devised by French botanist Patrick Blanc with architect Jean Nouvel, using a hydroponic system hung off the facade. The living wall holds 85,000 plants from both Australian native and exotic species, and in 2013 it was described as the world's tallest vertical garden. Look for the circular "Central" sign at the centre of the lower facade.

The retail centre at the base of the towers is naturally lit and open to the public, while the residential floors above are private. The site lies on the northeastern corner of the Central Park precinct, a short walk from Broadway and Central station. The cantilevered heliostat is best seen from the surrounding streets and the adjacent park.

The cantilevered platform on the taller tower holds a heliostat of motorized mirrors that redirect sunlight onto the gardens and the retail atrium below; after dark the same array carries LED work by light artist Yann Kersalé. The gardens themselves were devised by botanist Patrick Blanc as a hydroponic system hung off the facade, which forced Besix Watpac to revise the original cladding design.
