Nakagin Capsule Tower in Tokyo has some similarities to this concept. https://en.wikipedia.org/wiki/Nakagin_Capsule_Tower https://en.wikipedia.org/wiki/Nakagin_Capsule_Tower > The building is composed of two interconnected concrete towers, respectively eleven and thirteen floors, which house 140 self-contained prefabricated capsules. Capsules can be connected and combined to create larger spaces. Each capsule is connected to one of the two main shafts only by four high-tension bolts and is designed to be replaceable. The idea didn’t catch on however, and the building will likely be replaced in the coming years.
