Recent social trends - the diversification of lifestyles, and revitalization of the sharing economy - has led to significant changes in the fundamental functions and residences, particularly in apartments. Therefore, this study aims to define an optimized residential space by analyzing housing forms and lifestyle change factors. The study further categorizes the characteristics and operation system in an integrated living space including the integrated experience design characteristics and organization system for service content development and operation. The study scope and methods to classify the characteristics and systems of integrated experience design in integrated housing are as follows: First, the characteristics of changes in housing forms and lifestyles were defined through literature and previous research. Second, in-depth interviews were conducted, and the study direction was established using the analyzed factors of space experience design. Third, the structure concept of living platforms and the systems for implementing experience design were classified using the actualized space experience design characteristics. This study focuses on the basic concepts and systems for implementing integrated experiences in residences. Subsequently, it approaches the direction and systems for changes in housing as a unified platform. This study provides a framework that can be theorized using the experience design system for living spaces derived from its results.
