Resilient Habitat: Sustainable Housing Solutions for Landslide-Prone Area, Rangamati, Chittagong, Bangladesh

Idea projektu

This project addresses the critical need for safe and resilient housing in regions vulnerable to landslides. The proposed design takes into account the unique challenges posed by unstable terrain and aims to provide sustainable, 'Chakma' community-centered housing solutions.
Context and Idea
Natural disasters, such as landslides, often lead to the displacement of vulnerable communities, especially in rural and hilly regions. This project focuses on creating housing clusters that are not only disaster-resilient but also culturally appropriate and economically viable for the affected communities. The design incorporates local materials, traditional building techniques, and modern engineering strategies to minimize environmental impact while ensuring structural stability and functionality.
Goals and Objectives
Safety and Resilience: Develop structures that can withstand the pressures of landslides through stilt-based foundations, appropriate material selection, and land-use planning.
Sustainability: Utilize locally available, Eco-friendly materials like bamboo, wood, and tin while integrating passive cooling and ventilation techniques.
Community-Oriented Design: Foster social interaction and inclusive by creating shared green spaces, communal courts, and spaces for agricultural activities.
Adaptability: Provide housing options tailored to different income groups, such as single-bedroom units for lower-income farmers and two-story homes for middle-income jobholders.
Environmental Integration: Preserve and enhance the natural landscape by dedicating 57.7% of the area to green spaces and utilizing water bodies for sustainable drainage and aesthetic enhancement.
This project represents a holistic approach to disaster-resilient architecture, blending innovation with cultural sensitivity and environmental stewardship. It underscores the vital role of architecture in enhancing the safety, dignity, and well-being of communities living in fragile ecosystems.
