Renovation plan for the restroom area in an existing Chinese restaurant. I reviewed the design of the path leading to the restrooms and proposed a major change in direction compared to the original interior design. I also planned the renovation of the restrooms with a change in the area of the compartment, and completely renewed the design, including partition planning, water supply and drainage, and air conditioning. As a result, the changes were not only cosmetic, but also met the client’s needs, especially in the area around the hand wash basin and in the booths, which were greatly expanded.
