Several streets in Melbourne’s middle ring could be set to gain dozens more residents, as a string of older homes or empty blocks are listed for sale with permits for apartment or townhouse developments.

Sites across the city’s leafy south-east and north-east are slated for higher density projects, but some residents are concerned.

In Templestowe, three detached houses with large backyards at the end of Yolande Court could become 19 townhouses after developer Campi Homes bought the land and applied to Manningham Council for a redevelopment permit.

The council refused the application but Campi Homes took the case to Victorian Civil and Administrative Tribunal and won.

A group of local residents who opposed the project had a minor win, with more than 50 conditions added to the permit to build, but some are still unhappy it could go ahead.

One Templestowe local who declined to be named told Domain he was disappointed his area could soon be significantly busier despite the local community’s best efforts.

“The whole system is stacked against the residents,” he said. “All of us residents have to organise to get off work which costs us money.

“Then you have to decide if you want a lawyer or not which can cost $150 an hour.”

Their major objections were around the major influx of residents and traffic in a generally quiet area, which could be congested at times due to traffic from a nearby school.

The blocks of land have now been listed for sale with the approved permit, and the Jellis Craig agent Andrew Keleher said the developer wasn’t worried about the bad blood with the locals.

“Once they build they won’t have a relationship with the residents so it’s not a concern at all,” he said.

While residents felt there were too many homes planned for the nearly 8000 square metres of land, the developers could have built even more, Mr Keleher said.

“The permit was obtained for 19 homes. Each unit is on about 300 square metres of land,” he said. “They could have squeezed about 27 or 28 on but they went for more substantial blocks of land.

“Realistically, residents fight the fight, but if it’s in the scope or what’s legally allowed it’s going to get approved.”

Agents in conjunction on the deal are Jellis Craig’s Nicole Qiu and CBRE’s David Minty, Julian White and Chao Zhang.

In Toorak, another project could soon add more residents to one of its most prestigious streets.

Hopetoun Road is home to some of the largest estates in the postcode, and No.8 could soon lose one such landholding and gain a luxury apartment block with six Rob Mills-designed units after being listed for sale.

The building, to be built in the style of a typical Toorak mansion, should be slightly more popular with locals than some other developments, RT Edgar agent Mark Wridgway said.

“They’d appreciate it once it’s there. While they might prefer not to have apartments, I don’t think they’d be disappointed when they see the final product.”

Mr Wridgway said the developers had originally listed the permitted block for sale to free up capital for other projects, but were now considering retaining the Hopetoun Road site and finding alternative methods to fund their other work.

Harcourts agent Tony Che was selling two development sites in a similar position, one on Burwood Highway in Burwood and another on Clayton Road in Clayton.

Both were ready to build, but were being offloaded by developers having difficulties trying to secure funding to credit issues and a weakening property market.

“Banks have tightened up with construction loans,” he said. “This is the reason developers are actually selling good projects.

“They can make money on it if they have financial support but it’s not there at the moment.”
