This spring semester 2020, architect Wonne Ickx from PRODUCTORA was invited to teach a studio at RICE University in Houston, Texas as the Cullinan Visiting professor. The studio was called 'Pyramid Schemes' and combined an interest in the early XXth Century housing projects by Henri Sauvage, with a project site in Mexico City and an analysis of the related local conditions. The studio started out with quite some travelling forth and back between Houston and Mexico City, including a week-long study trip of the RICE students to Mexico's capital.
