The Street Design Challenge is a 48‑hour international competition for university students from UNESCO Creative Cities to reimagine real streets as safer, more playful and caring environments when seen from 90 centimeters which is the approximate eye level of a 3‑year‑old child. Streets that work for young children and their caregivers tend to be safer, healthier and more inclusive for everyone.​ Organized by the Cities of Design of Detroit, Muharraq, Doha, Wuhan, Asahikawa and Queretaro Creativo, the 2026 edition invites new ideas for child‑focused streets that improve everyday life for local communities.
