The '"Gungjeong Social Housing' project was carried out for a new residential space experiment for the millennial generation of Korean society. For the younger generation in Korea, residential space is turning into a private space and, at the same time, a community space in loosely solidarity with people of similar tastes. They are seeking the possibility of living and sharing various convenient spaces together because of the expensive housing costs in Seoul. In this project, community lounge cafes will be planned for use by residents on the first and second floors, while the remaining three floors will have a shared house that can accommodate a total of 11 people. Four people reside on each floor, and there will be a shared kitchen with a high ceiling on the top floor. The project was designed by combining CLT and reinforced concrete structures to save construction cost by shortening the construction period. In particular, the CLT structure was applied to the bedroom space to provide young people with the opportunity to live in a healthy, wooden space at a low cost. The space where water-related facilities are laid, such as toilets, showers, boiler rooms, laundry rooms, and kitchens, was planned with a reinforced concrete structure to minimize the possibility of defects.
