DESIGNING CO-LIVING SPACES: OPTIMISING SPACE FUNCTION FOR THE COLLECTIVE NEEDS OF FAMILIES AND COMMUNITIES

Abstract

The rapid growth of co-living as a contemporary housing concept in urban areas has created an urgent need for interior design strategies that can accommodate the diverse lifestyles, activities, and backgrounds of its residents. This study

focuses on optimizing the design of shared spaces in community-based co- living environments, with the primary objective of enhancing comfort, social

interaction, and spatial flexibility. The research adopts the Design-Based Research (DBR) method, which integrates five stages: contextual problem analysis, formulation of initial design solutions, implementation and exploration through semi-structured interviews and participatory observation, reflection and refinement of design iterations, and final evaluation based on comfort, functionality, and social usability indicators. The findings reveal that major design challenges include the absence of clear spatial zoning, limited

natural lighting, suboptimal ventilation, and the inflexible use of fixed, non- modular furniture. These issues were addressed through the application of

ergonomic principles, the integration of balanced natural and artificial lighting strategies, and the introduction of flexible, modular furniture to support dynamic spatial arrangements. Furthermore, the adoption of the Japandi style— combining minimalist Japanese aesthetics with the warmth and functionality of Scandinavian design—proved effective in creating spaces that are visually calming, practical, and conducive to both productivity and communal interaction.In conclusion, this research demonstrates that DBR provides a robust framework for generating contextual, adaptive, and applicable interior design solutions for co-living environments. The proposed design not only achieves aesthetic value but also strengthens the role of shared spaces as collective hubs that promote community engagement, personal comfort, and modern communal living.
