Located on a challenging longitudinal plot, the challenge is to create a new form of vertical mixed development on top of a subway station. The design strategy aims to revisit the relationship of a built environment with the street, focusing on the interface at both city and human scales. Tower volumes are designed to create an interplay of heights to whilst integrating voids to create multiple public spaces. The open retail concept at the podium generates generous public spaces at the street edge, allowing for visual and physical engagement with the city.
