Recycling and reusing materials is a form of exploration that manifests itself in our work, as well as in our collaborations. Abraham Cruzvillegas and Pablo Pérez Palacios met at the botanical gardens of the National Autonomous University of Mexico, where they found a fertile ground to investigate the possibilities of unfinished pieces. The proposal for collaboration that emerged from their encounter was based on a dialogue between Cruzvillegas’ artistic proposal developed over the years around self-construction, and the architectural language of PPAA. Drawing inspiration from an unfinished wall of volcanic stone they found at the botanical gardens, as well as scattered debris and gravel mounds in the landscape, Pablo and Abraham decided to use the debris and gravel to complete the missing half of the wall. The result is a continuous line that defines the space in a distinctive way and leads to an ideal platform for the contemplation of the natural reserve.
