"Okoshi-ezu is an ancient and almost forgotten form of Japanese paper architectural modelling, in which construction information is communicated to the craftsman through a model that folds flat. These models can be thought of as a sort of traditional pop-up, being erected and held together using an elaborate system of tabs, hooks and inserts — notes on the drawing indicate materials, dimensions, and textures.
"Okoshi-ezu, which first appeared in sixteenth century Japan, was most often employed for the documentation of teahouses, a highly refined building type which emerged at that time … Teahouses were carefully designed and custom made, and recording such specific design intentions required the development of a new drawing type — the okoshi-ezu. This method of documentation speaks to the level of trust in the craftsman’s skill, but also to the type of buildings that are generated from it. Often these designs reflect a spatial complexity that is subtly resolved in seemingly simple formal elements."
