This study examines the principles and considerations for age-friendly housing design in social housing development. Through a comprehensive literature review and content analysis of design guidelines from various countries and organisations, the research identifies core principles of age-friendly housing design, including accessibility, safety, comfort, and social integration. The study also explores specific design considerations for interior and exterior spaces, as well as the integration of technology to support independent living. Implementation challenges, such as cost considerations and retrofitting existing properties, are discussed alongside case studies of successful age-friendly social housing projects. The findings highlight the importance of adopting a holistic approach to age-friendly housing design that addresses the diverse needs of older adults while promoting sustainability and community integration. The study concludes with recommendations for implementing age-friendly design principles in the Latvian context and suggests areas for future research. The research contributes to the growing body of knowledge on age-friendly environments and provides practical insights for policymakers, urban planners, and housing developers involved in creating inclusive and supportive living spaces for aging populations.
