The start point of this project is the research of single person household. According to a presentation from the Swedish government, in Sweden, the family structure is changing as time goes by. After 40 years, there will be more than 40% of household are single person households. In addition, The project aims to create a sharing furniture, which used in living room, for young single person households. By using this furniture, they can enjoy the time being alone at home and also enjoy the leisure time with others, for example, through the Swedish social phenomena - fika. The delineation of study and research of my project is furniture design towards single person households and fika. The theories I applied include sustainability, life cycle, human needs, and design methodologies. Sustainable design put sustainable development theory into the design process, let the ecological environment and economic development connected as an the reciprocal causation. It lead to the use of energy resources effectively, and reduce the environmental pollution to the lower degree. To achieve sustainable design theory, each steps within product life cycle need to be considered in a sustainable development way. Sustainable design principles not only refer to the design process, also stressed in engineering process, the production process, the sales process, the use process, the storage process, the maintenance/repair process and retirement process, to reduce resource consumption, to build a new production and consumption oriented concepts to achieve sustainable design. The main practical methodology within the entire project and process is participatory design. Participatory design encourages all the users to directly design by using the simple tools, then do creative jobs by themselves and make own improvements during the process of practice. Furthermore, the participatory design can promote the users to realize the true value of designers, and finally they can also enjoy the conveniences which are brought by these designs.

The number of young single-person households is consistently increasing in South Korea, as in Sweden where the most common type of household is the single-person household. Housing is the key to the transition of young adults to adulthood and it can affect their quality of life and economic security throughout their lifetime. However, young people have encountered a similar housing problem in Sweden and South Korea, countries with different social, cultural, and political backgrounds. This study explores the policy implications garnered from Sweden for establishing housing policies for young single-person households in South Korea by investigating the difference between the housing policies in Sweden and South Korea and the rental housing provisions for young single-person households. The policy implications for single-person households in South Korea are, first, increasing the supply of rental housing and easing housing support requirements to provide housing to more young people as an alternative to increasing the universality of housing welfare policies. Second, providing the applicants' with applications and contracts on a single platform through an online integrated housing support system can be expected to improve operational efficiency and provide better convenience to residents. Third, a method of supplying a variety of housing to each region through regional integrated dormitory supply utilizing an integrated system, and satisfying the demands of the housing consumers, can be considered to establish an effective housing policy.
