This case is a traditional building in a street with two units on the first floor merged and converted into a dental clinic. With a total interior area of about 135 square meters, the original building structure has a long depth and a lack of height, resulting in limited natural lighting. In addition, the focus of careful and comprehensive planning includes the waterway, piping, equipment configuration, staff movement, etc., which are indispensable for a medical clinic to be professional in the future.
