1st Prize: BCA Innovations in Concrete & 2nd Prize, International Concrete Design Competition. A paving slab whose appearance and texture change in response to pedestrian traffic, creating a visual and tactile record that adds functionality and character. Every pedestrian becomes a participant, inscribing the history of that space’s use, and creating a form of intuitively understood signage.
