To begin the construction process, Odico Construction Robotics in Denmark created a mold for the alternately rectilinear and sinuous concrete forms. The mold was cut into shape by a 7-axis, robotic abrasive wire-cutting arm, which sliced and formed it like a giant lathe. (The mold is made of expanded polystyrene, a close cousin to Styrofoam that’s stronger and denser.) Working from CAD drawings, this diamond-tipped, articulated bandsaw runs on custom digital-fabrication software, cutting through mirrored forms that play to concrete’s strengths and cover up its weaknesses.
