The Impact of Housing Space Standards on Adaptability in Affordable Multifamily Housing: An Analytical Study of User Modifications in Sulaymaniyah, Iraq

Affordable housing has evolved to meet the difficulties of increased demand by offering acceptable living spaces for middle- to low-income families and facilitating access to housing units based on their annual income. This research seeks to investigate the relationship between housing spacing standards and family desire for affordable multifamily housing. It sought to address the changes that were occurring in the internal spaces of multi-story housing because of the inhabitants’ evolving needs. The study investigates the habitability of 25 residential apartments within 6 affordable multifamily housing compounds established in Sulaymaniyah city in Iraq in accordance with Iraqi housing standards. The results show that the rise in family size was the key reason for the considerable physical changes and enhancements that families made to their units. Crucially, the study found an explicit relationship: the wider the difference between the actual habitable space and the minimum Iraqi standards, the more frequently modifications occurred. This implies that inflexible space standards fail to fulfill the actual needs of low-income families, forcing occupants to make alterations despite the possible deterioration of the unit’s internal environment. The study contributes to the discourse on affordable housing in Iraq by offering empirical evidence of household-driven change and underscoring the necessity of incorporating adaptability into future affordable housing design policies.
