As a pavilion for children’s play, we would like to awaken the children's senses and create new play spaces. This site area is located in an outdoor exhibition space, surrounded by concrete walls dotted with openings. The installation is largely composed of three materials: pink, flexible height bars, white balloons, and aluminum wires. The kid’s movement and the touching of the bar will be transmitted to the balloon, causing it to move. The project budget was $4000 for design, installation, and maintenance for 6 months. How can we create a structure that embraces both space and generation within it?
