The number of dementia patients in China accounts for the largest proportion in the world, but not enough attention is given by the society. Through the architectural research on fuzzy boundaries I found that open buildings can increase social skills and improve happiness for dementia patients. Older adults who experience memory loss need a space to move safely that can help them go over this difficult period on their lives. I developed my project to create a half-day nursing center for patients with several types of demential (Alzheimer, etc…) allowing them to be in a familiar environment that will increase well-being and slow down the process of brain deterioration. At the same time, knowing their relatives are in a safe and enriching environment allows the families to be calm about them through the day. I looked at several references, worth mentioning, the half-open building of Fuji Kindergarten by Tezuka Architects where I learnt about the functions in a creative educational rounded spaces. The dementia daycare center consists of two circular buildings. The first is smaller semi-open space used for sports and entertainment, focused on more physical activities; the second is a two-story building used to meet the basic living and leisure needs of the patients, more focused in mind and social stimuli. In addition, the surrounding design of the green space will help patients to clearly identify the location of the two buildings, and the wooden fence is set up at the boundary to ensure the safety of the elders. The old Chinese saying: “Honor other aged people as we honor our own”. Gradually forgetting the loved ones around us is a painful process, we need to be full of empathy in the process of caring for them, and help them remember better through the details of architectural design.
