It is to assume that the art of curved folding as process driven formfinding method can offer an easy-to-build alternative to expensive and unsustainable double curved freeform surfaces. Firstly, because, similar to 3D programs, it allows us to change the algorithm of the curves very quickly (a single piece of paper, only scores, no cuts, no glue), keeping the design
 in an ongoing process where the varieties are endless. Secondly, the geometry and mathematics of paper is very strict, and even though curved folding allows us back to romantic, personal expression, the rules of the paper transform our free formed curves into strict, geometrical form. Hence, the act of architectural form giving is seen as analog to the act of folding and unfolding, wrapping and unwrapping.

After the design of a roof for the Gleisdreieck station in Berlin had been set, the model was 3D scanned and 3D printed.
