Urban happiness is one of the key indicators of quality of life. The present study aims to comparative analyze the impact of urban design components on the happiness of residents in two heterogeneous neighborhoods of Qom; Bajak II (gradually formed texture) and Pardisan (planned texture). The research method is a survey-analytical type and data were collected through a researcher-made questionnaire with a sample size of 400 people in each neighborhood and data analysis was performed using Spearman correlation test, exploratory factor analysis and multivariate regression in SPSS software. The results showed that the pattern of the impact of the components on happiness in the two neighborhoods is significantly different. In Bajak II, the regression results assigned the highest weight to environmental perception and aesthetics. Factor analysis also showed that the residents of this texture perceive the components in an integrated mental structure (6 factors) with a focus on social capital and physical function. In Pardisan, the highest explanatory weight was assigned to the components of green space quality and walkability. Factor analysis of this context revealed a disparate mental structure (10 factors) centered on security and compensation for basic physical needs. These differences are due to the fact that residents of this neighborhood seek to compensate for physical gaps, while in Bajak, the priority is to maintain visual advantages and improve the quality of existing environments. The final conclusion confirms that urban design policies should be targeted based on the neighborhood need pattern.
