Résumé:
This research offers a critical reflection on contemporary urban development models in
Algeria, particularly those based on vertical densification and large-scale planned cities, such
as mass housing programs like AADL. While efficient in terms of capacity, these models
often lead to disconnection from local contexts, loss of identity, and high environmental and
economic costs.
As an alternative, the study explores horizontal densification as a more flexible and
sustainable approach, better suited to local urban and semi-rural contexts. It focuses on
intermediate housing models, such as Dense Individual Housing (HID) and Mixed Housing
(MH), which offer a balance between density, privacy, and spatial appropriation, while
avoiding uncontrolled urban sprawl. Through a contextual analysis of Sidi Serhane
(Bouinan) and international case studies (e.g., Vauban, Borneo-Sporenburg, BedZED), the
research develops a strategic framework based on land adaptability, social cohesion, placebased
memory, and self-building logics. The findings demonstrate that horizontal
densification can produce affordable, ecologically sound, and culturally embedded housing,
responding effectively to today’s housing challenges.
The study aims to contribute to the redefinition of urban paradigms in Algeria, moving
away from imposed vertical models to support a more contextual, participatory, and gradual
urbanization. It serves as a strategic tool for planners, architects, and decision-makers
seeking to produce housing that is resilient, inclusive, and truly rooted in place.
