SOM and Fender Katsalidis reveal plans for high-tech towers in Sydney, Australia

Skidmore, Owings & Merrill (SOM) and architects Fender Katsilidis have won an international design competition for a landmark project at Sydney’s Central Station in Australia

The new development seeks to rejuvenate the city’s busiest transport interchange with a new, vibrant public realm, and bring two tech-focused office towers with the world’s first AI-driven facade system, powered by 100 per cent renewable energy to Central Business District.

The $2.5 billion commercial development will contribute to Tech Central in Sydney's Central Business District. The design by SOM and Fender Katsalidis is set to transform the western edge of Central Station.

New commercial buildings and public realm improvements will enhance this southern gateway to the CBD, revitalizing and reconnecting the precinct to the city, and complementing the City of Sydney's plan to create a third new major civic square. The project is realized in partnership between developers Dexus and Frasers Property Australia.

The design for Central Place Sydney features two 37-and-39 story commercial towers, woven together by a low-rise building anchoring the development and enlivening the precinct at street level. Landscaped public spaces surround the buildings, enhancing connections between neighboring communities and the city's most prominent commercial axis. 

Located at the southern edge of Henry Deane Plaza, the central building is a dynamic urban form that shapes the precinct's identity. It ascends in a series of tiers, which are staggered to open up garden terraces and views at each level.

The curved sandstone forms respond to the scale and materiality of the precinct's existing character. The ground floor is highly permeable, accommodating a retail experience that flows into the plaza, while the upper commercial levels will be linked to the new towers to create campus-style floorplates.

"The building anchors the southern edge of the Plaza and combines creative workplaces, collaborative and community spaces, and active ground level retail along an internal pedestrian laneway," said Scott Duncan, Design Partner at SOM.

"We aimed to create a place that's engaging both at street level and in its broader urban context," Duncan added.

A core element of the Tech Central precinct, the project will encompass approximately 150,000 square meters of office and retail space. It will be one of the most sustainable commercial developments in Australia, with workplace environments that integrate nature and a range of amenities. 

Fender Katsalidis Design Director Mark Curzon says Central Place Sydney will be defined by its contribution to the city, new civic plaza, and sculptural office towers.

"Central Place Sydney’s focal point is a major new civic space wrapped with activated retail edges, enriched by two commercial towers and a landmark central building. It will redefine the precinct, completing Sydney’s vision for a ‘third square," said Curzon.

The architecture evolved from the overall urban planning strategy: two towers are expressed as three individual forms in order to reduce their visual density. Their distinct shapes read as a family, while each tower retains its own identity in terms of height, scale, articulation, and materiality. The building podiums are clearly distinguished from the towers above, each with a height, massing, and material palette that complements adjacent heritage buildings.

"The design establishes a new civic space that extends into the workplace—blurring the lines between public and private, while producing a highly vibrant and diversified experience," said Duncan.

The public spaces are designed to allow pedestrians to flow efficiently through and within the precinct. Each floor is conceived as a unique "neighborhood," connected by winter gardens, mixed-mode environments, light-filled atria, and outdoor terraces. The buildings will be naturally ventilated via operable windows and an automated facade system.

The workspaces are highly flexible, with the possibility to be combined and expanded both within and between floors. These adaptable spaces can accommodate technology companies as they evolve in scale and continuously shape their culture.

"The sculptural towers are shaped by the movement and civic connections at ground level and extend vertically into a ‘fine-grained’ skyline, orientated to address key vistas in a gateway configuration," said Curzon.

The "breathing buildings" concept extends to a holistic consideration of how architecture relates to its environment. The buildings are shaped to mitigate wind forces and admit natural light, while the computer-controlled facade shades the interiors from direct sunlight and reduces heat gain.

Central Place Sydney will be the focal point for the burgeoning Tech Central precinct and civic space, which also includes the new headquarters for software development company Atlassian.
