This is an experimental attempt to mathematically express the generation process of the complex volume layout of buildings in Ginza, which has been shaped by revisions to the Building Standards Act and district plans, using an algorithm.

​

By gradually fitting single volumes arranged in an even grid into the existing streetscape (white volumes), a volume is formed that follows the rhythm of the Ginza streetscape. By randomly selecting volumes at a specified density from the final volume created, a "pseudo-Ginza" emerges that is neither Ginza-like nor Ginza-like.

​

When a volume that has been algorithmically trained to represent the characteristics of a city's streetscape is applied to another city, how will humans perceive that city?
