The development of modern housing has been accompanied by less attention paid to the versatility and the variation of the living spaces. The quality of residential spaces has declined to a degree that the home has merely become a place to meet physical needs and many psychological problems have been neglected. Recognizing the factors affecting the environmental capabilities of today’s housing and design for improving the quality of life can create a desirable effect on the residents’ satisfaction. The present study was conducted to achieve the satisfaction of residents with creating a diversified and versatile (adaptable) space and investigate the effect of flexibility components on their satisfaction level. For this purpose, a residential complex in Isfahan (an Iranian city) was selected as the case study. This qualitative research was performed using library studies, field survey, and questionnaire. By examining the concepts of flexibility, the theoretical framework of the research was extracted. Then, according to the research’s background, the valuation of housing units was done in 7 plan types and three plan types with the highest average score were sampled. Finally, 38 residents of these units were questioned. The results showed that among 9 components effective on the concept flexibility, three factors of visual diversity, air moderation, and spatial hierarchy in all studied units are most important in terms of listener’s questions and play a significant role in the satisfaction of the residents of the flexible atmosphere. تفاصيل المقالة
