for his master of architecture graduation thesis from politecnico di milano, chinese architect Bojing Qu has proposed a series of rotating plug-in capsule apartments for shanghai. the design began with the observation that thousands of young people flood into the mega city as urban sprawl increases every year. it becomes urgent for them to survive with a limited amount space and higher housing rates. consequently, the idea of a rotating apartment has been conceived to produce a living system enclosed by a light gauge steel structure that can quickly be produced and assembled on site. individually, each capsule is made up of two main parts: one is a rotating component that involves the main daily living functions such as a living room, bed room, and dining room, while the other is a fixed module that contains the subsidiary functions such as a kitchen, toilet, and storage room. this system challenges the minimum living dimensions of human beings and multiplies the space available to them simply by rotating.
