The temporary installation was designed by Polish architects Ola Wasilkowska and Michał Piasecki who developed it as an exploration of changes and context of public space and how user-built structures could evolve. The seed of the design came from a series of algorithms manipulated to provide structural soundness. As participants began the assembly process they were encouraged to add to the design layout by manipulating space and adding “furniture” or human scale seating and platforms designed into the overall structure. This had the effect of the structure spreading out. The building process had layers of predetermined design and spontaneous space creation which then became indistinguishable.
