The architecture and interior design of the Sugamo Shinkin Bank in Tokiwadai, Tokyo, Japan sought to create a relaxing and refreshing space for customers. Architect Emmanuelle Moureaux arranged 14 different colours in a distinctive rhythmical pattern for the windows of the building, and designed silhouettes of trees for the façade. A constellation of leaves in 24 different colours are painted on the interior walls and glass windows, blending with the real trees in the courtyards.
