Tianjin has evolved into a city of icons. In contrast, we proposed a design that is defined by an intelligence derived from a thorough understanding of the individual unit. The two congruous residential towers exploit its elementary square plans to allow for a variety of unit types and vertical public spaces.

The Twin Towers’ generic shape is a thin veil concealing a radical and innovative approach for housing in the 21st century.
