Construction workers have hit a key milestone on a $1.2 billion commercial office building in North Sydney, topping out the tallest building in the region.
Multiplex has celebrated the topping out of 1 Denison, a 158-metre tower designed by Bates Smart Architects and developed by Winten Property Group.
The milestone means the tower is the tallest building in the Northern Sydney area.
Winten Property Group Development Director Stuart Vaughan said it is a significant milestone for the business.
“We are demonstrating our commitment to job creation in North Sydney and helping stimulate the growing local economy. 1 Denison is an exciting commercial project that will set a new precedent for office towers in North Sydney
“Over 80 per cent of the building is now leased to several high-profile corporate companies including Nine, Microsoft and SAP. SAP recently expanded from 5,700 to 9,400 square metres and is located on levels 11 to 15.”

When completed, more than 6000 people will reside in the building.
To date, more than 2700 construction workers and 36,400 cubic metres of concrete have been used in the delivery of the project.
Multiplex Regional Managing Director David Ghannoum said the company is pleased to have achieved the milestone for Winten.
“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,” he said.
“It’s a busy site in a precinct experiencing revival, and it’s great to be a part of it.”
The building has a total net lettable area of 61,600 square metres across 39 storeys and is is expected to achieve a minimum 5 Star Green Star rating from the Green Building Council of Australia as well as 5 Star NABERS rating and Gold WELLS rating.
The office tower features a perimeter core with floorplates ranging from 1336 square metres to 2518 square metres across three rises, a two-level lifestyle precinct and basement parking for 225 cars.
The project is scheduled for completion in September 2020.
