In a design competition commissioned by Youngjo Housing Co., Ltd., the consortium of JUNGLIM Architecture and DA Group was selected as the winner and awarded the contract for detailed design. Under the vision of “SEAPOS 21,” a futuristic high-tech city filled with the scent of the sea, the entire complex is divided into four zones: DIGIPOS, based on ubiquitous technology; EDU-POS, featuring school facilities and an English village; WELL-POS, centered around a sports center; and CUL-POS, which embodies an affluent neighborhood. This design successfully integrates TECHNOLOGY, COMMUNITY, and RESORT LIFE. The project site is a residential complex located within the Sinho Local Industrial Complex (designed for a population of 20,000) in the Busan-Jinhae Free Economic Zone. It boasts a pristine natural environment, surrounded by a migratory bird sanctuary and a coastal pine forest neighborhood park, where nature and people coexist. Serving as a supporting city for the Noksan National Industrial Complex and Renault Samsung Motors, and adjacent to the Jisa Science Industrial Complex and the New Busan Port, it is a nature-friendly new residential complex that functions as a high-tech industrial complex and a hub for transportation and port logistics, while also serving as a marine garden city in the Nakdong River estuary region.
