Green Square Town Centre | McGregor Coxall

• July 19, 2010

McGregor Coxall were awarded the lead consultant role for the public domain design of the Green Square Town Centre in South Sydney. The work follows on from the international competition the firm won for the masterplan of the urban centre in 2001. This sustainable metro village project is located over the Green Square station on former industrial land and is the largest urban renewal in the country. 5500 residents and 7000 workers will use the centre once the ten year, $1.7 billion project is completed.

ECOLOGICAL ENGINE

The proposed Green Square Town Centre metro village designed by mcgregor+coxall is located over the existing Green Square station in Sydney on contaminated industrial land and is the largest urban regeneration in Australia.

The government developer Landcom intends that 5500 residents and 7000 workers will use the centre once the ten year, AUD$1.7 billion project is completed. The design proposes public and private uses including three urban squares, a new park, community facilities, library, cinemas, bars, residential, commercial and retail facilities.

These are arranged along a restored urban waterway and green spine that traces the original creek. The project is powered by an ecological engine that delivers recycled storm water & renewable energy to the project. Water is a scarce and precious commodity and is celebrated across the public space.

FLORA

Locally indigenous planting forms the floristic palette for the park and Sheas Stream green spine. It performs a key role in the biofiltration system and will create a biodiverse fauna habitat for local birds and ducks.

STORM WATER HARVESTING & BIOFILTRATION

The water harvesting system intercepts polluted storm water from the 250 ha upstream urban catchment that flows directly beneath the town centre in a concrete pipe. This water is diverted to the surface and into the park and urban stream where it is cleaned through biofiltration. Water from the plaza and surrounding roads are also diverted into the filtration media. The water is then collected for storage. The project provides ecological services by improving the quality of the Canal and Bay downstream.

NON-POTABLE WATER REUSE SYSTEM

The naturally filtered water is stored in the tanks where it is available for non-potable reuse. The ecological engine will provide 90% of the water needs of the entire project including all the residential and commercial uses. The urban stream rises and falls in response to rainfall in the catchment while flood water is diverted under the site in extreme events.

HYDROLOGICAL SYSTEM

  1. Stormwater diversion from culvert
  2. Biofiltration cells in urban stream
  3. Urban stream & pond system
  4. Filtered water holding tanks
  5. Harvested roof water
  6. Water feature circulation
  7. Non-potable water supply to buildings
  8. Filtered excess water to culvert
