Adding a program to two different buildings on different coordinates is the main challenge of this project. How can a structure nest on two existing programs, using their performing structure while having the least impact? Designing a grid structure that can hang on six specific points of the towers while having the least contact is a suitable form for this kind of structure. This nested grid functions for commercial use. It includes vertical and horizontal paths or corridors, where shops take place, making it a three-dimensional maze(commercial). The grid creates open door spaces that enable different public activities to occur, making it a hanging city on the towers. The towers’ access cores rise in between the grid’s horizontal space where the towers can function uninterrupted.
