Property developers Third.i and partner Toohey Miller have tapped boutique tier-one construction company Roberts Co to build the $650m Warada on Walker project in North Sydney.

The Third.i project received development clearance from council earlier this year, and construction is expected to begin by the end of the year, with a completion date of 2025.

The region is buzzing with construction, with the listed Stockland recently receiving approval for a 51-story tower in Walker St. Simultaneously, developers ranging from Lendlease to Pro-invest have plans.

Roberts Co will deliver the waratah-inspired project while adding to its own busy calendar of more than $1.2 billion in projects across Sydney and Melbourne.

JLL has been recruited as the project's leasing agent, with global architecture firm Woods Bagot driving the design. Generate Property Group has also joined the project as a delivery partner.

As North Sydney emerges as a major capital destination, JLL is also advising on capital partnering alternatives.

Each average floor plate spans at least 1000sq m of interior space and consists of 22 levels of premium office and co-working spaces with over 27,000sq m of nett lettable area.

Warada on Walker was conceptualised amid the height of Australia's 2019 bushfires and the coronavirus pandemic, assisting in the shaping and creation of one of Sydney's first post-pandemic workplaces.

Third.i co-founder Robert Huxley is sure that Roberts Co will get off to a good start. The developer has entered into an ECI to manage the risks of price inflation, which the developer described as "an issue we’re seeing across the country."

“We see this building playing a major role in North Sydney’s return to the national stage as a genuine CBD of Australia. I can’t wait to see this project sprout across Sydney’s skyline,” Mr Huxley said.

The project will comprise 73 automobile parking spots, 156 bike parking spaces, 12 retail spaces, and cutting-edge end-of-trip facilities. It will also have a co-working space as well as a full-size amphitheatre. The project will be crowned with a large, 1,000-square-meter roof top garden with expansive CBD views. It is being developed to 6-star Green Star standards, with a target environmental rating of 5.5.

Jason Fraser, Principal of Woods Bagot, described Warada as "something special, the likes of which Sydney has not seen for some time."
