This project aims to improve the ADM public space. My project is oriented to improve the quality of the student lounge at the second floor of the ADM Building. The student lounge is a place for students to relax or study quietly, so I came up with the idea that I should provide a place which can hold alot of interesting books, and also can let students have a short break there. This bookshelf with sofa is the result of a research and observation of student behaviors. The bookshelf has enough space to hold a large amount of books, and have more space for people to sit there enjoying the books.
