This year the International High Rise Award has been won by 1 Bligh Street in Sidney Australia designed by Architectus with offices in Sydney in association with Ingenhoven Architects of Frankfurt, Germany.

The tower was conceived with three important considerations in mind: the view, the public space and the work environment. Its curvaceous plan also resolves the age old question of who gets the corner office. In this layout around 40% of inhabitants are within 4.5m of the glazing.

The elliptical form of the building is arranged to give the best possible views of the spectacular harbour.

In the architects words: “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.”

Internally there is excellent natural light and good air quality. The building achieved an 6 Star Green Star sustainability rating thanks in part to its innovative fully shaded double skin façade that incorporates a passive ventilation system.

Amongst other awards, the building has won The Harry Seidler Award for Commercial Architecture and The National Award for Sustainable Architecture, both highly regarded Australian awards.
