Lendlease has unveiled a civic building and urban square plan that will come up in Sydney's new inner city village, called Darling Square.
Design for the six-storey building has been done by Kengo Kuma Architects (KKA) while an adjoining public square has been designed by Aspect Studios.
Darling Square will have around 4,200 residents and 2,500 workers.
The plan is subject to approval of the planning authorities.
The building is known as Darling Exchange and will feature a library, childcare centre, and a rooftop bar and restaurant providing views over Tumbalong Park, the Chinese Gardens and Cockle Bay.
According to the design plan, light-coloured wood will wrap the curved building like ribbons.
KKA founder and principal Kengo Kuma said: "This is our first building in Australia and we are honoured to be the architect.
"Our aim is to achieve architecture that is as open and tangible as possible to the community, and this is reflected in the circular geometry that creates a building that is accessible and recognisable from multiple directions.
"The wooden screen wraps the exterior of the building in a dynamic and exciting manner, a historical reference to Darling Harbour originally being a hive of business activity and a focal point as a market exchange."
The building also will feature a 'makerspace' and Innovation Exchange, which will support technology start-ups.
Darling Square and Darling Exchange are being developed by property firm Lendlease.
These projects are being developed as part of the $3.4bn revamp of Darling Harbour, reported Dezeen.
Lendlease CEO and managing director said: "We are delighted to launch The Darling Exchange, together with the City of Sydney.
"Throughout history, civic buildings and public squareshave brought the community together.
"Our sincere desire is that The Darling Exchange will become a vibrant heart of the local community and a meeting place for all Sydneysiders and visitors."
