A Counter-Project for a Low-Rise, High- Densification as an Alternative to AADL MassHousing

Abstract

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.
