This proposal (2006) by French architect François Blanciak is located in the Japanese capital Tokyo. The 500m² complex called Yoyogi Building by the Tokyo-based architectural firm was supposed to include housing units, several shops and offices.

Project description:

‘On a plot adjacent to Yoyogi Park, the building — a usual combination of commercial, residential and office spaces — is the result of the collision of 23 spheres of identical radius, which fuse inward to differentiate various spaces by vaults rather than walls.

The seemingly random stacking of these elements allows groupings to create larger rooms when appropriate or divisions into smaller ones when cut by inner floors. The remaining outer membrane of the structure is cropped as it meets the boundary defined by city building rules, thus providing diverse diameters of openings to match the respective functions and locations of the rooms.
