Songpa Y`Z the Sharp’s design concept is a cultural village ‘Terra Walk’ that holds the memory and footsteps of the Wirye Castle. The project is located at the center of Wirye New City’s Transit Mall, which is expected to have abundant floating population. But big amount of shopping areas spread along the transit mall and comparatively small scale shopping component in this project may result in a competitive commercial activity. And also the residential facilities are located directly beside the Transit Mall that may cause inadequate living environment due to noise and invasion of privacy. So to solve this issue, the shopping areas had to be planned separately within the Transit Mall and the residential district to be planned facing the South side while considering the location of the shopping areas.
