The Rubinstein Group has recruited Jennifer Binetter and Carmen Culina to focus on development sites, collective sales and acquisitions across Sydney.

The pair’s appointment follows their work co-leading a collective sale of a 1960s apartment block in Sydney’s eastern suburbs – a deal that exceeded $30 million and involved 39 individual contracts across 35 residential studios and four commercial tenancies.

Ms Binetter and Ms Culina first connected as owners within the building, which required significant upgrades.

Rather than pursue a traditional refurbishment, they explored a collective sale to a developer.

“We recognised the limitations of a traditional refurbishment and identified a more strategic opportunity,” Ms Binetter said.

The off-market transaction required aligning multiple stakeholders and securing owner support across all lots.

According to the agency, some owners achieved up to double their property’s market value through the sale.

The site has since settled and is being brought to market by The Rubinstein Group as The Rushcutters.

Ms Binetter holds a PhD in strategic communication and decision-making, with a background spanning consulting, startups and venture capital.

Ms Culina’s experience includes law and technology advisory work across major project delivery in government and the private sector.

“The Rubinstein Group has built an exceptional reputation for performance and high-quality transactions. It’s a natural fit for the way we approach our work,” Ms Binetter said.

“The team’s focus on premium assets and strategic opportunities aligns closely with how I work with clients,” Ms Culina added.

Gavin Rubinstein, founder of The Rubinstein Group, said the pair’s experience with complex transactions made them a strong addition.

“Jennifer and Carmen bring a sharp, strategic skillset to the business,” Mr Rubinstein said.

“Their ability to manage complex transactions for clients makes them a powerful addition to our team.”

The appointments add to The Rubinstein Group’s eastern suburbs operations, with both agents now specialising in development sites and acquisitions.
