The Catalyst Cube was the result of a year-long engagement with the British Council that included a week-long public space workshop in Caracas and a design collaboration between London-based architect Will Sandy and Caracas-based firm Incursiones to create a small prefabricated structure that could occupy public spaces in informal settlements. This moveable, multi-functional cube is designed to inspire social, cultural and educational exchanges, creating an instant neighbourhood focal point. The Catalyst Cube is a tool for engaging citizens in the future permanent design and uses of their urban environments. The flexibility of its design and configuration allows it to support a diverse range of activities, from basketball games and exhibitions, to community events and neighbourhood meetings. As a catalyst, its objective is to increase the opportunities for interaction, exchange and development in its context, with the hope that these activities gather enough momentum so as to continue when the structure moves to its next location. The Cube can help to identify opportunities in the neighbourhood, giving people the agency to define and curate public spaces for themselves at a time when cities physical and social fabrics are in constant flux.
