This article explores the potential for rental housing in existing single-family home areas in the suburbs of Prague through soft densification. It opens a discussion on the possible incremental transformation of these unsustainable locations, responding to their circumstances, including the current housing affordability crisis and demographic aging of the population. The aim of the research is to quantify the spatial reserves in the built-up areas of municipalities that would allow for the development of housing units without the need to occupy new land. Through GIS analysis, more than 31,500 plots in 40 municipalities strongly affected by suburbanization were examined. The results show significant spatial reserves for the creation of additional housing units, either on the plots or inside family houses within their spatial reserves. The study confirms that the adaptation of the existing stock of family houses represents a significant and yet untapped source of housing units,that would lead to increasing population density, supporting social sustainability, and more efficient use of infrastructure in satellite municipalities.
