Community parks provide essential ecological and social functions in rapidly urbanizing and densely populated cities such as Karachi. This study investigates the relationship between park design characteristics and user satisfaction and park utilization through an in-depth case analysis of KDA Family Park, a neighbourhood park in a high-density residential area of Karachi. A case study research approach was employed, integrating structured questionnaires and field observations to collect comprehensive data from park users and adjacent residents. Key design characteristics evaluated included green cover, amenities(seating, lighting, pathways),accessibility, safety, and maintenance. Findings indicate that while KDA Family Park provides essential green space and functions as a valuable social hub, various design and maintenance deficiencies, such as broken fencing, inadequate lighting, and insufficient seating, detract from its overall effectiveness. As a foundational study, it offers insights for urban planners and policymakers aiming to enhance neighbourhood park design in Karachi and similarly dense urban environments.
