Efficient space plans are built upon relations of both human and physical compositions, and the standard of the interaction is basically the human scale. Especially in medical areas, the character of the users within human scale design environment is quite significant. Unlike large hospitals with great plans and scalability performed by experts, mid-sized clinics tend to have limited space, designed by non-specialists who highlight aesthetics over functionality in floor plans which leads to poor quality in medical service. For this reason, this study will include the application of human scale based therapy rooms within the clinic from a physical standpoint and will further analyze and pinpoint any room for improvement to further enable more efficient ergonomic space planning. In this study, theoretically will contemplate over human scale, mid-sized clinic, therapies, and therapists, while the case study will include status of the recent human scale based mid-sized clinic from a physical viewpoint, classification and analysis amongst human and physical compositions chosen by discretion from either a newly opened or a newly re-modeled clinic within the last 2 years, which has 15 beds or more, minimum 3 physical therapists, with more than 5 different therapy facilities in the metropolitan area in order to measure the human scale of therapy rooms in a mid-sized clinic. As a result, the area where improvement can practically be applied is the physical composition, which does not include human scale like human composition factors as therapists and patients, and hence, I suggest the human scale applied efficient medical space plan become the base of this study and look forward to subsequent improvement in the quality of medical services.
