This project explores the relationship between children and play through toy design that supports cognitive, motor, and creative development. By studying child psychology, play patterns, and age-appropriate activities, created several innovative toy concepts, including building blocks, puzzles, and interactive kits. The final concept, Story Town, allows children aged 6–12 to construct modular 2D-to-3D pop-up towns with accessories like houses, trees, and vehicles. The design encourages both solitary and group play, fostering storytelling, town planning, environmental awareness, and civic sense through hands-on, imaginative interaction.
