Through the COVID-19 pandemic, non-face-to-face social activities increased, and these changes remain in our daily lives to this day. Accordingly, the residential space has been transformed into a space where various activities, such as work and hobbies can be performed, not just for housing. In addition, the number of single-person households is gradually increasing, and among them, young people in their 20s and 30s account for a large proportion. The Co-Living House, a residential type suitable for these changes in lifestyle and the characteristics and preferences of single-person households for young people in their 20s and 30s, was designed. The theme of this building is 'Modular Co-Living House with a Multi-Functional Envelope’, and it has a structure in which a diagrid outer envelope surrounds the building built by the modular method, and it is a multifunctional envelope that plays an environmental and structural role.

The wind blowing into the building changes and flows according to the shape of the building. Using the blowing wind for natural ventilation is a nature-friendly idea, and it makes the building more attractive that it is happening inside the sensuous facade. While constructing the facade in this way, we tried to design a building with an outer envelope that functions for natural ventilation. The laminated modular structure is stable in the lower floors, but there is a problem that it is more vulnerable to lateral load as it goes up to the middle and high floors. In contrast, instead of the existing core method, we tried to solve this problem by structurally using an outer envelope that functions as an environment.
