Third.i to deliver 300 apartments in Marrickville TOD precinct
Sydney developer Third.i has announced a new transport-oriented development in one of Sydney Inner West’s most sought-after metropolitan locations, delivering much needed housing within steps of world-class public transport and vibrant village life.
Located at 31-41 O’Hara St, Marrickville, the proposed mixed-use development will include around 300 apartments, with up to 17 per cent dedicated to affordable housing, reinforcing Third.i’s commitment to creating inclusive, well-connected communities that support a diverse mix of residents who keep Sydney’s neighbourhoods thriving.
Located just 100 metres from the new Metro station, the development places residents within minutes of the CBD while offering seamless access to the Inner West’s cafés, retail, and local services. Anchored within a thriving local centre, the project supports everyday living without reliance on cars, while also delivering new public open space for the local community, including a new park and landscaped green areas, alongside high-quality private resident amenities.
Florian Caillon, Head of Acquisitions for Third.i Group, said the project builds on the company’s ongoing work alongside the NSW Government to deliver housing and amenity alongside major transport infrastructure. Amenity includes an activated pedestrianise retail strip that connects Illawarra Road down to the pocket park, and health and wellness facilities.
“Delivering housing of this scale within an established village is a rare opportunity, and few companies have achieved residential outcomes of this size at a village centre," Caillon said.
"We are excited to set a new standard for urban living in the heart of Marrickville,” he said.
The inclusion of affordable housing has been welcomed by frontline workers.
“We are supportive of developments which will allow essential workers like nurses, midwives and carers, the opportunity to live in the communities they care for," said Michael Whaites, General Secretary of the NSW Nurses and Midwives’ Association..
“Many healthcare workers tell us they would like to live closer to where they work, but are being priced out of the market, forcing them to move further away.
“Dedicated apartments for essential workers will support recruitment and retention in local hospitals and aged care facilities, helping to strengthen our health system.”
The project has been declared State Significant Development (SSD) by the Housing Delivery Authority (HDA).
