Liverpool Council has decided to go ahead with buying 48-52 Scott Street, Liverpool, which has 186 car-parking spaces and the potential for more.

Deputy mayor Ned Mannoun fully supports the Scott Street purchase.

"This is a fantastic investment — it's an investment for the people of Liverpool," he said.

"It's an opportunity for us to build a car park on top of what's there at the moment.

"It would also provide an income."

Part of the site is leased by the Department of Corrective Services and Crunch Gym.

Cr Mannoun said it would also provide an opportunity for the council to lobby the state government for funds for a car park.

He said previously the only other potential spot council could build a car park was in Bathurst Street but added that to develop there would primarily benefit Westfield shopping centre.

"The southern end needs a car park and some revitalisation," he said. "I see this as a fantastic site with a lot of opportunity."

Cr Mannoun said no money was being borrowed for the purchase but admitted it would most likely be a paid parking site.

A council report on the benefits of the purchase said it could be amalgamated with the School of Arts site and income from the leases and car park could provide a return, allowing for possible long-term redevelopment.

The council previously contemplated buying it as an alternative to 33 Moore Street - their current administration centre - which they bought in April for $19.1 million.

"We now really need to look at the bigger picture."
