Housing is one of the fundamental human needs, extending beyond a mere physical place to live. It signifies a home—a space of identity, security, privacy, and social inclusion. Its value increases with age, as it becomes associated with memories, accomplishments, and a sense of belonging. Among Slovenians, housing holds a special significance, as the majority are homeowners, with house ownership predominating. Owning a house represents more than just property—it is a symbol of independence, stability, and a connection to the natural environment. It embodies the fulfillment of life goals and reflects a culturally ingrained ideal. Slovenians are also traditionally reluctant to move, so those who built houses in the past have mostly remained in them for life. Houses were typically built as multi-generational residences, with the expectation that children would also live in them. In many cases, however, children moved out, leaving their parents alone. Consequently, many large family houses became half-empty or even fully vacant. In the context of modern demographic and housing challenges, large family houses with underused or vacant living spaces represent significant housing potential. The purpose of the research project is, therefore, to develop possible models for the activation of large family houses with vacant or partially used living space. These models will include technical and legislative adaptations, organizational solutions, and incentive proposals.
