BIG’s latest project, the Cross # Tower, takes four minimalist high-rise blocs and combines them in a jarring gravity-defying tic-tac-toe composition. The 280,000 square foot complex consists of two towers that act as pylons to brace the other two blocs, which have been flipped on their sides and suspended in the air. The resultant “#” form achieves a delicate weaving of solid and void, of private and public space, that connects different sections of the complex mid-air. The tower, which is being planned for Yongsan International Business District of Seoul, envisions a new, close-knit residential unit, whose inhabitants are endeared to one another by the services and community space afforded to them by the structure’s form.
