Secret Maps addresses the relationship between form and narrative. Narrative has been an operative force in architectural design since antiquity and has taken on different readings and expressions throughout its employment in design, varying from basic shelter (meeting primal needs) to more complex agendas (such as collective identity and propaganda). We gauged narrative in this project as described by Tschumi as secret maps and impossible fictions that inform sequences and programmatic functions. Narratives a such imply found spaces amidst progressive frames that depend on one another. They are concerned with event(s) as opposed to function(s). They seize spatial opportunities instead of merely abiding by required parameters. As such, we were charged with imagining such spaces within two formal hybrids: an eroded cube and a grid structure. The cube was the subject to an erosive process, delivered by us, but controlled by the reactive nature of foam and acetone. Contrarily, the grid is directly modified and altered by us in response to the eroded cube or contrasting it. What is the result of integrating two different formal systems? How does the topology of one object inform the other? This cross-pollination yielding hybridization and transformation carries a multitude of spatial possibilities and activates a number of common and peculiar events.
