4. Methodology for
Developing Design Criteria
Studying the Existing Efforts:
ā¢ Analyzing stakeholders and organizations involved in
low-cost housing for disaster prone rural areas
ā¢ Studying existing practices on low-cost housing for
disaster prone rural areas by various organizations
HBRI
UN-HABITAT LGED
BRAC
BUET
CARITAS-BD
RED-CRESCENT

5. Methodology for
Developing Design Criteria
Regional Identity and Variations Aspects:
ā¢ Mapping vernacular house patterns
ā¢ Mapping local building materials, construction practices
and technologies
ā¢ Mapping natural hazards
ā¢ Mapping regional climate and geography
ā¢ Mapping settlement morphologies

13. Methodology for
Developing Design Criteria
Adaptation Strategies with Natural Hazards:
ā¢ Mapping house damage patterns
ā¢ Acceptable limit of damage by natural hazards
ā¢ Risk reduction; Damage reduction
ā¢ Selection of building materials
ā¢ Selection of structural systems
ā¢ Appropriate construction techniques: Iindigenous and
improvisations
ā¢ Selection of house forms
ā¢ House position and orientation
ā¢ Rural spatial planning/ neighbourhood planning
ā¢ Emergency shelters and disaster management plan
ā¢ Tree plantation
15. Methodology for
Developing Design Criteria
Acceptable Limit of House Damage:
ā¢ Total hazard-proof is costly
ā¢ Retaining skeleton
ā¢ Reusing building materials
Adaptation
Strategies
16. Methodology for
Developing Design Criteria
Building Materials and Techniques:
ā¢ Using local materials
ā¢ Durability enhancement of
local materials
ā¢ Introducing appropriate
new materials and techniques
ā¢ Reusing traditional materials &
techniques
Adaptation
Strategies

17. Methodology for
Developing Design Criteria
House Form, Orientation, Spatial Planning
and Disaster Management Planning:
ā¢ Using stable roof form
ā¢ Orientation not facing wind
& water surge direction
ā¢ Compact settlements
ā¢ Rural spatial plans
ā¢ Integration with disaster
management plans
Adaptation
Strategies

18. Methodology for
Developing Design Criteria
Cost Minimization and Local Employment:
ā¢ Minimizing cost by design coordination; Group of NGOs may
have same design
ā¢ Minimizing cost by design, building material, house forms,
facility sharing
ā¢ Using local materials/ production on site
ā¢ Engaging local labours
ā¢ Enhancing Durability and recycling possibilities of building
materials
ā¢ Incremental development and future extension possibilities
19. Methodology for
Design Development
Placing Design Criteria in Local Context
Physical Aspects:
ā¢ Analysis of site and soil
ā¢ Local building materials and technologies
ā¢ Local climate and topography
ā¢ Neighborhood morphology/ clustering

20. Methodology for
Design Development
Placing Design Criteria in Local Context
Socio-Economic Aspects:
ā¢ Income of the users/ budget
ā¢ Profession/ way of living of the users
ā¢ Household size and structure
ā¢ Social/ neighborhood structure

21. Methodology for
Design Development
Placing Design Criteria in Local Context
Userās Need Identification:
ā¢ Identification of space requirements of the users
ā¢ Identify facility requirements of the user
ā¢ Financial needs
ā¢ Building maintenance training needs

22. Methodology for
Implementation
ā¢ Partnership of international and national
organizations
ā¢ Partnership of national and local organizations
ā¢ Building up local capacities for construction and
for quality control
ā¢ Quality assurance mechanism
23. Crosscutting
Issues
ā¢ Actors in Low-Cost Rural Housing for
Disaster Prone Areas
ā¢ Institutional Set-Up
ā¢ Quality Assurance
ā¢ Dissemination of Knowledge
ā¢ Spatial Planning/ Land-Use Planning,
Environmental Aspects and Integration
ā¢ Financing
