Infinity by Crown group, the so-called ‘landscape tower’ designed by Koichi Takada Architects, is nearing completion after five years in the making. the practice won the project in 2014 through the city of Sydney design excellence competition, during which the team has overcome a series of design and construction challenges to deliver a stand-out piece of architecture. as the scaffolding is slowly being removed, the structure is just beginning its unveiling, with an expected completion in early 2019.

Infinity is located on the corner of Bourke street and botany road, a gateway site to green square, a new town center in Sydney. the 20-story building is designed with the idea of ‘cities within cities’, containing a total of 40.000 sqm of truly mixed-use functions, which include 325 apartments, 75 boutique hotel rooms, 30+ retail and F&B outlets, a 450-seat conference center, and a direct connection to the green square train station.

Koichi Takada has designed the landscape tower using terracing and level changes to connect the building from multiple angles. this approach creates an experience of being within the landscape, just like Sydney’s undulating topography. ‘the idea of the landscape tower democratizes tall buildings,’ explains the design team. ‘it is almost fighting against height, trying to push down as much as it can, to bring the experience down to a more human scale.’


“The shape adapted due to the environment, to respond to the sunlight, to create a relationship with the surrounding buildings, and really open the vista for the people who live around it.” Koichi Takada

The aerodynamic form draws air into the courtyard and facilitates natural ventilation through pressure differentials. The sculptural shape is carefully designed to give more sunlight back into the green square library and plaza (designed by Stewart Hollenstein in association with Colin Stewart Architects). The main library space is hidden underground and mostly relies on skylights for natural light.

A lot of people underestimate the shape of infinity,’ says Koichi Takada. We’re not doing it because we think it looks cool, it was something that we developed for a reason. The shape adapted due to the environment, to respond to the sunlight, to create a relationship with the surrounding buildings, and really open the vista for the people who live around it. The loop brings more daylight into the public plaza and in turn makes it a more pleasant place to be. the shape is just a result of this conversation with the environment, the context, and the neighbors.’
