Interstice envisions threshold conditions, through many scales, as community-builder spaces within multi-family housing. Bridging the largest scale—San Pablo Park a 3 minute walk away; to middle—public mixed programs along the street; to site—resident courtyards and pathways; to unit—kitchens, living rooms, and balconies. Working on an urban scale, and selecting a site along San Pablo Avenue in Berkeley, California, Interstice imagines a reconnected and beneficial new relationship along the historic avenue geared towards the automobile.
