Take a trip through the winding labyrinth of alleyways in a slowly deteriorating section of Gongdeok-dong in Mapo District of western Seoul and you may come across an unexpected sanctuary. Baik Soo-hye s compact outdoor garden abounds with some 150 potted plants, trees and herbs that were once thrown out or left for dead in urban redevelopment zones across Seoul as their former owners were pushed out of their neighborhoods to make way for new apartment complexes.
