With the scratches on Rose Hill, where else can Sydney build housing? Here are the seven potential sites | Sydney

High-rise blocks in Woollahra? Convert Glebe Island to housing instead of boats? Mobile Long Bay Prison? Established in Karan Park?

NSW Prime Minister Chris Minns has promised to unveil “Plan B” to repair the punches in the government's housing blueprint after members of the Australian Turf Club voted against the sale of the Rosehill racing venue to make room for 25,000 new homes.

The losses lost in the small city of Rosehill have caused the state to scramble to resolve the city's housing crisis.

Minnes said earlier this week that he was disappointed by the failure of Rosehill's proposal, but did not disappoint him.

“Even if the risk is failure, it is important to test these things because the task before us when housing in New South Wales is so huge that we can’t just take safe choices,” he said.

“We can't just place bets. If we make sure bets on each housing proposal and do nothing uncontroversial things that don't anger Nimbys Irate, there will be no action in New South Wales.”

Are there other websites that can be developed to promote housing in Sydney?

Grey and the Bay Area

The Bay Area is a large area near Rozel and Heidou Bay. It has been specifically used for development, but plans are in its early stages. It will have a subway station on Metro West Line, with existing plans already designated commercial properties and 5,000 homes.

The plan currently does not include the development of a port facility in Glebe Island, which was previously used to unload imported cars. Today, the port is intermittently used for overseas cruise ships suitable for the port bridge and for the batch processing of concrete for major projects including the Metro and Barangaro.

It is close to the city and the proposed public transport link, which means it can accommodate more housing.

Urban Taskerce CEO Tom Forrest said it will create a problem with almost no shadows for surrounding homes – which can increase density.

On the downside, this will lead to the loss of marine infrastructure in Sydney's ports.

When asked about the location in Parliament on Wednesday, NSW Planning Minister Paul Scully did not rule it out.

Sydney Olympic Park

Developers have already advocated greater housing density in Olympic Park to replace Rosehill.

The 2050 master plan requires 13,000 new homes, but the developers say the 43 hectares of website can accommodate more.

The advantage is that the Olympic Park is located on the West Metro Line and has good sports and leisure facilities. On the downside, plans are progressive and changes may delay development.

Karan Park

The Metropolitan Western Front is directly under a 62-hectare government-owned waterfront location in Rozelle, once home to Callan Park Hospital.

There is no plan now, but a station can be added, just as the government has proposed an additional station for Rosehill.

However, the site is now Parkland, with several stone buildings on the heritage site. Development, especially high-density housing, will allow the government to collide with residents and heritage experts in the inner west.

The state government also owns the site of Gladesville Hospital on 25 hectares of Victoria Road, although it is not on the metro line. Now it is used in certain medical facilities and is listed in heritage.

Woollahra Railway Station Area

Sydney Yimby chairman Justin Simon is an advocate for allowing more density in the eastern suburbs. He noted that in the 1970s, there was a partially built station on the Eastern Suburb railway line due to residents’ objections.

Simon said the government's Transport-oriented Development (TOD) program does not include any eastern suburbs. The plan allows development of a transport center within 400 meters and can reach up to 30 floors in the case of accelerated areas. The policy has led developers to propose several locations on the Sydney North Shore.

Simon said the forgotten Woollahra station may be developed soon, with developers eager to assemble out of the site from small holdings as they did on the North Shore. “We will call for very tall buildings,” he said.

Likewise, the proposal would be in line with the resistance of residents and heritage experts, as unified Victorian housing is characteristic of Woollahra.

Camellia and ATC land more density in Rosehill

The government appears to rule out building a subway station in Rosehill after the proposed sale was rejected by members of the turf club.

But the area is still a good place for more homes and rail links, the developers say.

Rick Graf, development director at Billbergia, said the area remains a highly suitable location for high-density development and the government should consider a better subway station closer to the Camellia Town Center.

Graf, who is also the convener of the Rosehill-Camellia Land Owners Alliance, suggested that the current plan for Camelia (the old industrial area 1.5 km from Parramatta CBD) should be reviewed without cooking.

The current master plan envisages 13,000 homes served by Parramatta Light Rail and Ferry Terminal. But with the underutilized land that ATC owns around the racetrack, Graff said the area can support 25,000 homes on the 40- to 50-storey towers served by the subway station.

“The track may be part of the green space. In other parts of the world, arenas are being incorporated into the center of the track,” he said.

Graff said the camellia owners have not spoken to the government since the Rosehill program was defeated, but there is still a compelling case for the mini-cities in the area.

Relocation of Changwan Prison

Another state-owned website, Long Bay, is now used as a remand center. The 32 hectare site is served by buses from the ANZAC parade, but is only 5 km from Kingsford's last existing light rail station.

The prison needs to be relocated, but the proximity to the CBD and beaches will make it attractive for new housing developments.

Rebuilding Randwick Barracks

Since the 1980s, it has floated in the development of the 20-hectare Commonwealth-owned Randwick Barracks. It is relatively close to the last stop on the L2 and L3 light rail lines.

The current plan is for the Department of Defense to build 62 townhouses in a small part of the site to serve as a defense facility. The development is expected to be assessed by federal authorities this year and is exempt from state and local planning controls.
