Due to the issue of an aging society, the trend to design a living space that meets the needs of a family of 3 generations has become primary nowadays. Taking about 1300 square meters, this case is a narrow space with two constructions on the site. With a sky bridge and hallway that connects two of the buildings, the design allows privacy and independence while residents can keep in contact with each other. The building's overall style is composed of concrete walls and wooden lattices. The great size of the glass windows and the greenery around the space create a modern metropolitan vibe.
