THERE may be taller buildings in Australia, but with its vast footprint, the 49-storey C3 tower at Barangaroo is likely to be the country’s largest office building in terms of floorspace.
Developer Lend Lease’s detailed plans for the second and third major commercial towers at Barangaroo were placed on exhibition by the Department of Planning yesterday, providing the most accurate glimpse yet of the future for the $6 billion urban renewal project.
At 205 metres tall with 115,291 square metres of floorspace, the northernmost commercial tower, C3, will be the tallest building at Barangaroo; but there will still be eight taller buildings in Sydney including the Citigroup and Chifley buildings.
Designed by architects Rogers Stirk Harbour & Partners, the towers have large floorplates, curved contours and vividly coloured vertical shading panels on the facade designed to cut air conditioning requirements by up to 30 per cent.
Each tower will have fewer than 200 car spaces; with a total of 1200 bicycle spaces across the three towers as part of plans to minimise car trips and promote alternative transport.
The childcare centre, which was deleted from C4 plans, has been restored in C3, while the planned supermarket in the commercial precinct has been downsized to a ”fresh food market in the podium of C5”, a Lend Lease spokesman said.
A supermarket is likely to be part of the proposed residential towers to be built north of the commercial precinct, the spokesman said.
When complete, the three towers will provide almost 300,000 square metres of new office space in Sydney to house 24,000 workers; and 15,000 square metres of new retail floorspace at ground level.
Planning documents also proposed the use of ”responsive” digital landmarks beamed on to walls and building facades to help pedestrians navigate the new precinct. Completion of the three buildings, once approved, is scheduled for 2016.
