In 1964, a young Cedric Price joined forces with the successful theater director and producer Joan Littlewood to conceive a project with the ambitious goal of transforming the concept of leisure and education in post-World War II Britain, which was still recovering from the devastation of the war. The Fun Palace project, however, never materialized into a physical structure, leaving Price’s drawings as the sole record of its design. Employing cybernetic principles, the project was envisioned as a structural framework encompassing an interactive machine without a defined program, in perpetual transformation. It was like a board of combinations with no single solution, foreseeing the emergence of parametric architecture. Based on the collection of Price’s original drawings, this article presents a virtual reconstruction of the Fun Palace project. It includes new documentation and an analysis of the changeability of the constantly evolving elements that define the Fun Palace.
