Parti Wall is a workshop and an installation that exposes the architectural sensibilities of the 9 mentor-led teams that occupy the 9 modular cells in the grid. For the workshop teams of mentors and students were given our new problem set and then asked to negotiate over 72 hours the boundaries that define their respective spaces. The result blurs distinct architectural positions into a singular and at times tense formal coherence, and examines the 9-Square Problem as an endless void.
