Abstract: Urban park areas mitigate urbanization’s negative impacts by integrating environmental, social and cultural benefits. Development strategies should enable participation and consider all user groups’ needs, following sustainability principles. However, ensuring multifunctionality often generates conflicting decisions. While the universal necessity for safety is widely acknowledged, its implementation frequently results in the diminution of a crucial sense of privacy. For example, the universally recognized need for safety may compromise the willingness sense of privacy or intimacy. This can discourage those for whom this need is important and prevent urban parks from fully utilizing their social potential. This study examines how spatial configurations of plant forms within urban parks shape personal experiences. We used an intra-group design to evaluate photographs of park spaces, manipulated using Photoshop AI algorithms to examine safety, privacy, preference, and willingness to spend time. Variables included space size and shape. The study used Computer-Assisted Web Interviewing (CAWI) with 300 participants. Regression and mediation analyses showed willingness to visit derives from space attractiveness, influenced by perceived safety and privacy. Analyses revealed the following: open areas were safest but the least private, corridor spaces were the least safe but the most private; curtain screens enhanced perception better than corridor screens; small spaces with corridor screens were least attractive; space size mattered less for open spaces than screened spaces; and spatial configuration was critical in assessing small spaces. The findings of this research enhance our comprehension of the perception of park spaces. They hold potential practical implications for sustainable design, facilitating the development of plant forms that are more socially effective, particularly those with substantial environmental value, such as dense vegetation that serves as visual screens. Neglecting these preferences may result in inappropriate design decisions that fail to accommodate users’ needs and behaviors, thereby not fully capitalizing on the potential of urban green spaces.
