This research aims to provide a new way of thinking about the ever-expanding quest in architecture to deliver free-form geometry. Rather than relying on complex formwork, the proposed reconfigurable system can translate free form synclastic surfaces to pre-programmed 2D configuration, providing an attractive potential for the building industry. The work draws inspiration from the transformation process of auxetic materials and embeds this within a bi-stable mechanism. Starting from fundamental geometric research of linear hinges and out-of-plane rotation, geometrical constraints are identified thoroughly for the length-preserving transformation (Bottom-up process). Computation strategies to generate the locations of linear hinges from target discrete curvature are informed by the constraints and further optimized through prototype fabrication(Top-down process). Accompanying the pattern generation, a design strategy based on the Gauss map and parallel mesh is also developed to explore the given constraints of materiality and constructability(Bottom-up process again). Finally, practical proposals in three different contexts, namely, vertical screens, flexible molding, and self-supporting shell structures are designed to exhibit the wide-ranging applications of this system.
