The Mouri Detective agency takes up the upper two floors of a three story building. The second floor is the detective agency proper, and is where Kogoro meets potential clients and stores his files. The windows are lettered with "Mouri Detective Agency". The third floor is the Mouri family living space. Part of the floor space is a living room with a kotatsu and television. There is also a small kitchen and a bathroom. Kogoro's bedroom, which is shared by Conan, has a sliding door out onto a small balcony overlooking the street. The agency is accessed via a covered staircase to the right of Cafe Poirot.
