The study is based on the idea which is “Space enclosure” that encloses persons three dimensionally. The main purpose of the study reveals spatial characters of tea rooms which are very small but have colorful compositions. Also “Sight-Depth” is used to calculate three dimensional spatial compositions mathematically. Following explanations are the procedure to analysis.
1. Making digital models by CAD
2. Setting up the measurement positions in tea rooms and then calculates three dimensional compositions.
3. Making Self-Organizing-Maps based on the data of second step.
4. Making spatial descriptions.
5. Building up phylogenetic tree based on the spatial descriptions and then analyzes the tree.
