I made this 1:200 working model entitled ‘Playa Blanca, Bankers and the Pivotal Point’ during my time at the Städelschule Frankfurt. The three-dimensional knot bent from copper wire combines investigations into rotational symmetries, the programmatic linking of living and working environments, and early aesthetic explorations into the consequences of parametric design models. This physical model formed the basis for a series of digital models whose gene codes continue to shape the work of our office in terms of methods and aesthetics to this day.
