Winner of the DEXUS/City of Sydney design competition Architectus, in association with Ingenhoven Architects (Germany), created a highly sustainable office tower that has achieved 6 Star Green Star Office Design v2 and Office As-Built v2 Certified Ratings from the Green Building Council of Australia and a 5 Star NABERS Energy Rating.

Extending the ideas proposed in the Stage 1 DA, the proposal for 1 Bligh Street was developed with three critical considerations: the view, the public space, and the work environment.

The view
The corner of Bligh and Bent Street strongly marks the main address for the building. The elliptical form aligns with the grid to the north and is oriented to the harbour, maximising views and creating premium office space and a quality work environment.

The public space
The reduced building footprint creates a significant new public space for Sydney that allows deep soil landscaping and extends Farrer Place.

Broad curving steps rise to the sheltered wintergarden and provide an ideal place to sit in the sun and appreciate the full expanse of Farrer Place and the heritage buildings of the Education and Lands Department.

The work environment
The work environment is designed around the principles of ESD, flexibility, efficiency, communication and transparency.

A fully shaded double skin facade provides excellent Indoor Environment Quality (IEQ).

The structure delivers consistent large floor plates of up to 1600 m2 and achieves 92 per cent efficiency Nett Lettable Area to Floor Space Area.

Forty per cent of office space is within 4.5 metres of the facade with 1000 m2 contiguous column-free space creating high potential for office layout flexibility.

The elliptical plan is 12 per cent more efficient than a rectangular building in facade to floor area and allows excellent natural light penetration. The 120 metre high central atrium makes dynamic views accessible to all.

“This (1 Bligh) is the future for Australian office buildings, this is Australia’s most sustainable office tower, making the best possible use of the clean energy technologies that are available today, making the best use of the sunshine for generating power, making the best use of design so that the building minimises its energy costs, making the best use of water recycling too. This is a building that has been put together with energy efficiency, sustainability and clean energy at the forefront of everybody’s thinking.”
