“Hidden Boxes” is the product of history. Although the history of architecture has witnessed various concepts such as Raumplan, Domino, and Universal Plan, today’s architecture still emphasizes the production of monotonous spaces. Our focus was simultaneously on the internal issues of architecture such as spatial configuration, the Mass/Void relationship, relationship among surfaces, and the breaking of space as well as on the external issues of architecture such as climate, privacy, and the cultural needs of the subject of the project.
