SYDNEY Ice Arena could be knocked down and make way for a 20-storey mixed-use development.

Capital Corp has submitted a planning proposal to the Hills Shire Council on behalf of Sydney Ice Arena owner Hillsong, seeking to increase the maximum building height at 11-13 Solent Cct, Baulkham Hills to 20 storeys.

Councillors will vote on submitting the proposal to the NSW Planning Department at tonight's council meeting.

In support of the planning proposal, the developer provided a concept plan, which includes retail shops and restaurants on ground floor, levels one to four for commercial offices, a podium that has a pool and tennis court, and 15 storeys of residential flats within twin towers.

Capital Corp managing director Greg Taylor said the site is a great location for high-rise development.

"We've done 40 developments in the Norwest Business Park and we saw this as a good future development site," Mr Taylor said.

"It is close to the North West Rail Link Station and we've been working on this with council and the NSW Government."

The possibility of the Sydney Ice Arena being demolished will have ramifications on the national men's and women's competition clubs Sydney Bears and Sydney Sirens, who will be forced to find new homes.

Sydney Bears president and general manager Wayne Hellyer was shattered to hear that club may be forced to move out of The Hills.

"That's news to us. We have a three-year contract with Sydney Ice Arena that ends in 2014," he said.

"It's a real shame if it goes ahead because we were looking at renewing our contract.

"Australian Ice Hockey League games needs to be played in the best venues and the Sydney Ice Arena facilities are fantastic.

"Since we've been based in The Hills, we've had great support from the locals."

As a development application process will need to take place if the planning proposal is approved, Mr Taylor said any work on the site is still "a few years away".
