The project targets at the role of play in the city and regards play as a strategy to re-generate and recycle the city. A new housing scheme is proposed over the industrial urban context that offers more play space by recycling parts of factory ruins. The project aims at developing a more engaging and long-lasting play space responding to the government's cuts to the play service. The ruins are served as a permanent host for the ever-changing playground to enhance the local community to construct and de-construct with the waste material as play performance.
