Playgrounds is a traveling exhibition of the architecture of Mansilla + Tunon Architects. It was held for the first time in 2006 at the Harvard Graduate School of Design. Each project is stored in a box that serves as packaging and display. Each box contains a model and a graphic document that enables the understanding of the work. The exhibition has been shown at many architecture schools, architect associations and cultural centers of different countries. The collection of boxes is a visual archive of the office work.
