Research on modern heritage is attracting interest nowadays. For this research, we focused on the large housing estateof Climat de France, designed by Fernand Pouillon. We aim with this participation to provide alternatives like digitalinstruments to enhance these dwellings, articulating our research on the following problematic: How can thecontribution of space syntax be useful for carrying out a diagnosis and digitization of the Climat de France? Theresearch will be based on an integrated urban approach that combines spatial and geographical analysis. We will focuson understanding the different elements of space (roads, public spaces, the built environment, and physical attitudes)and describing the relationships between them in terms of connectivity, accessibility, nodality, and density, theseparameters will therefore require the use of software such as depthmapx. In conclusion, the study of the Climat deFrance using syntaxe could be an effective lever for safeguarding and valorization of this modern heritage.

French colonial mass housing estates built in Algiers between 1950 and 1962 constitute a substantial part of the city’s housing stock and continue to shape its urban structure. As aging residential environments, they present important challenges for sustainable regeneration. Despite their significance, the relationship between urban configuration and long-term physical deterioration remains poorly understood. This study establishes a georeferenced inventory of these estates by combining archival documentation and field surveys with Geographic Information Systems (GIS) and space syntax analysis. Configurational properties were quantified using Normalized Angular Integration (NAIN) in DepthmapX, while the physical state of each estate was evaluated through a systematic assessment of structural elements, façades, and public spaces. The results reveal considerable variation in integration and a statistically significant relationship between its levels and physical quality. Estates occupying more privileged positions within the street network generally exhibited better maintenance and higher-quality public spaces, whereas more isolated estates experienced greater deterioration. The findings suggest that street integration is associated with estate performance, providing quantitative evidence to support sustainable regeneration planning by proposing a practical decision-support framework for identifying evidence-based resilience planning and governance priorities.

Historic medinas across the Maghreb constitute fundamental components of urban identity, embodying centuries of cultural, social, and spatial continuity. Yet in many cities across the Maghreb region, historic urban fabrics have progressively become marginalized within rapidly expanding metropolitan structures. Modern planning interventions, infrastructural transformations, and colonial legacies have often produced spatial and functional disconnections between historic centers and contemporary urban growth. As a result, historic districts are frequently perceived as constraints to urban development rather than as active components of the evolving city. This research argues that the sustainable future of historic medinas lies not in their isolation or crystallization as heritage enclaves, but in their strategic reintegration within the contemporary urban system while preserving their spatial identity and morphological coherence. Focusing on the Casbah of Algiers as an analytical case within the broader Maghreb context, the study employs space syntax analysis to examine the relationship between historic urban fabrics and surrounding modern networks. Through this approach, the research seeks to identify structural opportunities for reconnecting historic centers with contemporary circulation systems without disrupting their intrinsic spatial logic. By proposing an integrative framework that reconciles heritage preservation with urban accessibility and connectivity, the study demonstrates that historic medinas can function not as obstacles but as catalysts for sustainable urban development. In doing so, the article contributes to current debates on heritage urbanism by reframing historic centers as active structural components of contemporary metropolitan systems rather than isolated relics of the past. In this perspective, the reinsertion of historic centers becomes a generator of urban vitality capable of guiding future growth while maintaining the cultural and spatial intelligibility that defines the historic cities of the Maghreb.
