Parramatta Council has given its support for a $35 million redesign of public areas at Parramatta Square, including the creation of a central fountain, winding watercourse, art installations and green spaces.

Last night, the council in Sydney voted in favour of the draft concept design, which will be put on public exhibition for four weeks.

The investment is part of the $2 billion Parramatta Square redevelopment that will include commercial, residential, educational and civic buildings.

Parramatta Mayor Scott Lloyd said the space would become a landmark for Parramatta upon completion in 2019.

"We all voted unanimously because we see this vision becoming a reality," Councillor Lloyd said.

"It'll truly be a destination. It'll enable people to connect between the light rail and heavy rail.

"It'll give people a place to meet up and give us a wonderful little oasis in the heart of the city."

Parramatta Council has hired a team of four internationally acclaimed design firms, including Danish architect Jan Gehl, to create the draft concept and connect the river to the city.

The team have won acclaim for their individual and collaborative work both locally and overseas, including projects in New Zealand, the United Kingdom and New York's Time Square and Broadway.

As well as the water features, the public domain will include digital wayfinding, a northern lawn, southern plaza, play garden, a new Town Hall lobby, focal artwork and multiple crossing points across the stream.

Cr Lloyd said Parramatta had a long connection with water and the design paid tribute to that.

"With the new design we're encompassing water right through the middle of the square," the Mayor said.

"It brings us symbolically back to our roots of a river city.

"People love seeing water fountains and water features throughout the city."

Western Sydney Business Chamber backs plan

Western Sydney director of the Sydney Business Chamber David Borger said the group supported the draft concept design as a good first step to bring new energy to Parramatta.

"This new design for Parramatta Square creates a solid foundation for the city's business growth and provides an attractive home for smart jobs in Parramatta," Mr Borger said in a statement.

Mr Borger said council needed to create an viable urban precinct where people spent time using social amenities, restaurants and bars.

"Parramatta Square will only work if it is integrated into the community, not sitting as a group of office blocks in the centre of town," he said.

"The new Parramatta Square needs to be the most accessible place in the whole CBD.

"Parramatta is on the way to building a strong night-time economy. The challenge is creating a public space that people want to spend time in."
