Auxetic geometry, which can be defined as geometry which expands in a direction perpendicular to a tensile force and contracts in a direction perpendicular to a compressive force, has found application at multiple scales within biology, textiles, aerospace, and the military. However, the kinetic nature of auxetics requires internal movement of the geometry when subjected to external forces. This movement often results in complex joints, making them difficult to fabricate and deploy at a larger, architectural scale. A conceit of this thesis is that geometric characteristics associated with auxetics make them ideal candidates for architectural application, such as their ability to adapt to synclastic (double) curvature and their ability to deform locally due to a stimulus. Out of Plane aims to investigate the potentials of auxetic geometry for architectural application, but also with digital and physical simulations of such applications in order to understand potential fabrication methods as well as design strategies for auxetic systems. With initial questions about the portrayal of auxetic patterning and the implication of the uniformly patterned systems that are typically represented, the potential of three dimensional auxetic origami systems is of specific interest. If the kinetic nature of auxetic geometries was to be exploited in conjunction with their innate ability to respond to local stimuli, it could be hypothesized that an initially uniform pattern could apply to countless different exterior and interior conditions.
