Thirdi Plans $1.6bn Central Coast Housing Community

Developer Thirdi has proposed a masterplanned community that promises no infrastructure costs for the NSW Government on the Central Coast. 

The 200ha Charmhaven Project site at Charmhaven on the Central Coast is located between the Pacific Highway and Arizona Road and is expected to cost $1.6 billion.

It would deliver up to 2000 homes with 120ha of protected environmental green space, a new school and a business park. 

More than 10 per cent of the project will be allocated to affordable housing for essential workers with the NSW Government not required to pay for any infrastructure costs. 

“If approved, the rezoning will allow us to provide critical, enabling infrastructure such as roads, water and electricity, which will benefit the wider region—all at no cost to the NSW Government,” Thirdi acquisitions head Florian Caillon said. 

Evolve Housing will handle the 200 affordable homes with workers able to rent the homes at below-market rates. 

“Our members keep our hospitals running day and night, but they are being pushed further and further away from their workplaces by skyrocketing housing costs on the Central Coast,” Health Services Union NSW assistant secretary Lauren Hutchens said.

“That’s why we’re encouraged by developments that make affordable housing a priority.”

The school, if approved, will be a low-fee independent Christian school for 1500 students.

The Charmhaven Project would be the largest housing project on the Central Coast and could deliver almost a quarter of the NSW Government’s target of 9400 new homes in the region by 2029. 

Thirdi is hopeful that the first new homes for the masterplan could be delivered within 36 months pending planning approvals.

The Central Coast’s population is expected to surge to 404,250 people by 2041, putting increased pressure on housing supply.

Thirdi’s current development pipeline exceeds $4 billion with completed projects across Sydney and Newcastle.
