In Indonesia, young adults comprise 33.75% of the population, with evolving lifestyles prioritising informal, collective, and creative living environments. In Yogyakarta, co-housing has emerged as a promising alternative for those seeking socially connected and supportive communities. This study examines the co-housing preferences of young adults through the Means-End Chain (MEC) framework, focusing on how personal values influence housing choices. Based on 50 questionnaires and three in-depth interviews, the findings highlight trust, social interaction, and community-building as the primary drivers of co-housing preferences. These insights suggest that beyond physical attributes, co-housing is valued as a space for fostering meaningful relationships, collective well-being, and a secure communal environment.
