A new "heart" for Molyneux Park in Alexandra is likely to cost up to $10.4 million.
A series of designs for the redevelopment of the 28ha park were unveiled last night at a media briefing.
They include the construction of a new "hub complex" and indoor sports hall, which would house an ice rink for six months of the year.
The plans also include relocating the existing netball and tennis courts to the space which would be vacated by the ice rink and building a new pavilion next to the cricket oval.
The concept designs cost $36,000, which was funded by the Vincent Community Board.
Board chairwoman Clair Higginson said the Molyneux Park working party, made up of board members and council staff, was initially looking at upgrading Molyneux Stadium.
"That led to this study of the whole park in a push for something that was more affordable for the community."
The designs were prepared by Beca Carter Hollings and senior designer Tonia Williams said her brief was to try to "future- proof" development at the park, co-ordinate facilities and create a "heart".
More than 30 groups, mostly sports clubs, use the park.
Its grounds are used for cricket, ice-skating, BMX cycling, bowling, squash, swimming, skateboarding, netball and tennis.
Molyneux Stadium is a venue for indoor sports and is also used as a gymnasium by nearby Dunstan High School.
The school planned to build its own gymnasium on its grounds, which would be available to the public.
"Once that facility is in place and we can gauge how widely it's used, we'll know what is needed to complement it with facilities at the park," Ms Williams said.
The stadium would be demolished in five to 10 years' time, so any redevelopment of the park would be done in stages and based on the needs of the community, board member Tony Lepper said.
The cost of a new entrance to the park, upgraded grounds, new courts and pavilion would be $4.2 million, while a new sports hub and ice rink would cost between $9.2 and $10.4 million.
The ice-rink floor would revert back to a flat sports floor for half the year.
"We're not talking about the council spending all that amount of money," Mr Lepper said.
"Obviously there's lots of different groups involved and they have their own needs and own funders."
"There's 32 groups to put into the mix.
This is only the first line in the sand."
The first major works planned for the park would be "significant" landscaping as a base for further development.
That was estimated to cost $300,000.
Mr Lepper said the plans will be considered by the board at its estimates meeting on Friday and will form part of the council's long term plan, once feedback had been received.
