A preventive health care community based on "family happiness" provides users with a peaceful paradise away from the hustle and bustle of the city, helping them treat diseases with confidence, rather than rejecting disease screening because of fear. The flexible structure supports the changes of different spaces, including health check, vaccinations, and acute illness, etc., and is committed to maximizing the efficiency of medical staff. Integrating health care into people's daily life and enhancing people's awareness of physical examination is the design motivation of Xanadu Clinic.
