Today, a city is composed of five factors of man, nature, infra structure, information and the earth. These factors form a huge network and work as complex media that connect man and city. Pentafort project is to realize these complex media into a structure. Pentafort is the core commercial complex facilities in Asan-Baebang area, a new town. This Pentafort will create a multidimensional and multicentric culture in developing nationwide station-influenced sphere and multi functional complex. Waterfront area that city meets nature will create an attraction in station-influenced sphere, and it is designed to play the role of catalyst for urban activation.
