This kindergarten is different from ordinary kindergartens in that it allows students to experience nature from the age of zero. The design also focuses on the concept of expressing the innocence and simplicity of a child. She aimed to keep the shape as simple as possible to leave room for creativity. She used a paper cutout-like form. She also included various creatures that children may encounter in the forest as motifs. She used Risograph for printing. Since they had a limited budget they used rough paper which is commonly used at schools and can express natural feelings.
