The contact surface of the green area is increased by forming Green Fingering, connecting Seokdae arboretum and Jangsan Mountain which is being built at its surrounding site.

Various types of residential spaces that share with nature are made, visitor areas and residential areas are separated for a pleasant environment, and a healthy community is formed through well-being facilities such as golf course, medical center, spa, and so on.
