The Infinite Happiness' offers an unusual architectural portrait of the “8 House,” a large-scale residential project designed by BIG–Bjarke Ingels Group in Copenhagen. Filmmakers Ila Bêka and Louise Lemoine spend a month living inside the building, exploring it as a “vertical village” and a proposed model for contemporary communal living. Through a mosaic of residents’ stories, the film constructs an intimate, human map of life within the structure. By revealing how architecture shapes everyday relationships, the documentary questions whether innovative design can truly foster collective happiness.
