This project was completed with Gustavo Crembil of Studio THEM as an entry for the ACADIA 2011 Design + Fabrication Competition: Sponsored by FLATCUT. It was selected for second place in the “Partitions” category. The exploration of hyperbolic geometry takes multiple forms and employs a series of principles that push our understanding of spherical and Euclidean logics. The pseudosphere is, in principle, a hyperbolic form generated from the elongation and exponential growth of a concentric geometry that is limited by a base geometric logic. The natural expansion of an exponential growth across a linear progression creates an excess in material that forces a principle pattern of undulation. This issue is explored in a modular expandable ceiling piece that is the result of a hybrid dialog between hand-craft and digital methods and thinking.
