Focusing on the behavior of maintainers in Ike- bukuro, this project aims to propose an alternative way to the maintenance free system and relying on repair services. Here, maintenance skills can be trans- mitted, acquired and practiced. People in Ikebukuro can bring their unwanted items from the city and re- cycle them into the things needed to run the building. When things used in this building break down, they can be brought here again for maintenance. The pic- ture (Image 3) shows the cycle of goods throughout the Marui Building from the aspect of maintenance.

The design process went through the following pro- cess. First, we observed the behavior of “MAINTAIN- ERs” in Ikebukuro and analyzed the tools, the sur- rounding environment, clothing, and how they relate to the object of maintenance. As a result, we were able to find a connection between each maintenance be- havior by focusing on the “gloves” they wore.

Secondly, we categorized each maintenance behavior by the “gloves” people use, and efficiently arranged tools, sinks and desks suitable for each behavior.

Finally, by connecting the zones divided by the types of “gloves” with desks, rivers, and hanging shelves, we designed a mixture that would create a transmis- sion of skills.

Affection towards building and cities depends on whether they can be SELF MAINTAINED. Therefore, by creating this floor, we are able to develop a stronger attraction to the MARUI Building and Ikebukuro.
