one-aftr was formed with the mission to create a 'collective good experience' in space. We use the vagueness of 'good' as a driving force of our inquiries.  We make sense of our surroundings through measured observation of everyday life and by considering viewpoints from other fields. We experiment with ways of working in  defining the 'good' through writing, making, curating, and building.
