FLOOD RESILIENT LOW COST HOUSING

Pabna University of Science and Technology (PUST)

Idea projektu

Between affordability and resilience. By utilizing cost-effective materials, raised housing structures, and community-driven solutions, the project ensures that migrants can continue their agricultural-based livelihoods while mitigating the impacts of flooding. Further studies on financing models, community engagement, and incremental housing approaches will strengthen the project’s affordability and long-term feasibility.

Popis projektu

Housing affordability and resilience are critical challenges for marginalized communities living in flood-prone areas. The Migrant community in New Maizbari Char, Kazipur Upazila, Sirajganj, Bangladesh, faces severe housing vulnerabilities due to annual flooding, river erosion, and socio-economic constraints. Since the land is a char (river island), residents do not own the land but rent it, making long-term investments in resilient housing difficult. This project aims to design affordable and flood-resilient housing solutions that adapt to local lifestyles, withstand flooding for 7-10 days, and provide safe, sustainable, and cost-effective shelter solutions without disrupting the existing agricultural-based economy of the community.Economic Constraints & Land Tenure Issues:
Since residents rent the land, long-term permanent housing solutions may not be financially viable.
Alternative financing models, such as micro-loans, cooperative housing investments, and NGO support, could help improve affordability.
Material & Construction Costs:
Low-cost, locally sourced materials (bamboo, compressed earth blocks, recycled metal sheets) can help keep housing affordable while ensuring durability.
Prefabricated, modular housing could allow incremental construction, reducing immediate financial burdens.
Flood Resilience Features:
Elevated Plinths: Raising houses by 2-3 feet using compacted soil or bamboo stilts can mitigate short-term flooding impacts.
Floating Elements: Incorporating amphibious foundations or modular floatation techniques could allow homes to adapt to rising water levels.
Drainage & Water Management: Community-based rainwater harvesting, elevated sanitation blocks, and natural drainage solutions can improve living conditions without excessive costs.
Community-Based Solutions:
Shared community spaces for resource storage, emergency relief, and livestock management can enhance affordability and resilience.
Encouraging collective land leasing or NGO-supported land agreements can increase security for residents, allowing them to invest in better housing.
