This project started with a single picture and expanded by a word, "open source". Instead of just buying and arranging things that are sold, try rearranging some parts, combining them with other products or sometimes natural materials, or applying a special rubber coating. We are open to free arrangement, customization, modification, and replacement. It would be interesting if this leads to the development of custom parts options by third parties in the near future. It would be like the relationship between the iPhone and the wide variety of iPhone cases, or the relationship between a car and tuning parts. It is a way of creating interiors that are tailored to your own specifications, without being bound by the specifications of ready-made products. We will hold an exhibition where you can fantasize about building a house half a step into the future using such "things that are beyond ready-made products."
