Winten’s $1.2bn 1 Denison Street Tops Out


Winten Property Group has “topped out” its new $1.2 billion commercial office tower—now the tallest building in North Sydney.

With its distinctive, inclined Bates Smart-designed facade, the 158-metre skyscraper at 1 Denison Street was built by Multiplex, appointed after Winten terminated a $200 million contract with Grocon amid a refinancing deal.

Winten development director Stuart Vaughan said the benchmark-setting project was a significant one for the business.

“We are demonstrating our commitment to job creation in North Sydney and helping stimulate the growing local economy,” Vaughan said.

“Over 80 per cent of the building is now leased to several high-profile corporate companies including Nine, Microsoft and SAP.

“One Denison will become a defining landmark on North Sydney’s skyline among several new hotels that are moving into the area.

“When completed over 6,000 people will reside in the building.”

Purchased for around $80 million in 2016, the site's location in the heart of North Sydney presented unique challenges, according to Multiplex’s regional managing director David Ghannoum.

“As well as installing curved glass panels to create the inclined façade, Multiplex has been challenged by the tight site, with building works occurring from boundary to boundary and many other large sites within close proximity,” Ghannoum said.

More than 2,700 construction workers toiled over the tower, which was delivered using 36,400 cubic metres of concrete and is expected to achieve a minimum 5 Star Green Star and NABERS ratings.

One Denison is scheduled for completion in September.
