“Interconnection”, “Interaction” and “Sharing” are the keynotes of this project. Located on an important gateway position, the layout of Twin Towers which formed a “visual corridor” in between was finally adopted, implying the existence of the urban spatial axis. The two towers can be separable and connected, interconnected and symbiotic, forming a dialogue relationship. Inspired by the local hilly terrain, the third floor and upwards adopted retreat platforms, growing upward and gradually separated into two towers, creating terrace spaces of different sizes, encouraging free communications.
