New products
Urbanization
Techniques for Construction
Soaring Costs
Sky high competition
Rural Housing
Housing issues Neglected
Housing issues Half-baked
Cost Effective Solution
Best Use of Locally Available Materials

Building the Vault in Nubian Way
A House in Auroville
Rural Housing
Green Bricks drying in the mud
Burning the Kiln
Finished with laterite earth, lime and cement

Effective Cost Cycle
Approximate Cost of the House Rs. 978
1086/- 19-22 per sq. m.
Cost of RD Rs. 3,000 60
Hence, Total Cost of the House Rs. 65,000/- 1,300
Return of Product Sales (Sales of Bricks) Rs.
45,000/- 900
The Actual Price Rs. 369/- 8 per sq. m.

A problem of Scale / Factors in Cost

• Large Scale Production System for more efficiency
• Government help subsidized loans
• Mud buildings are vulnerable to unseasonable
  rains when a large quantity of mud products has
  to be protected
• Invalidation of Process

• Foundation cost is high and the vaults fairly
  high
• Most of the work is unskilled i.e. moving bricks,
  loading unloading, adding cow dung/rice husks,
  clay over the vaults
• Due to its porosity exterior walls should be
  plastered with cement or lime based mixture
• Floors can be filled with fired product,
  interiors walls can be plastered according to
  budget

Conclusion / Materials for Future

• An Appropriate cost energy efficient technology
  that has a great future.
• Contributing to sustainable development
• Uses semi-skilled manpower
• Technology is easily adaptable and transferable
• The energy and monetary costs are much lower
• The vibratory atmosphere are very positive

• Variations of soil quality and hence blocks
  quality may suffer
• Soil with poor characteristics can cause
  shrinkages and cracks
• Mud buildings are vulnerable to unseasonable
  rains when a large quantity of mud products has
  to be protected

Finding connectivity

• A connection to Builders Yard ????
• Nucleus of entirely different and more personal
  relationship between builder and community.
• In the case of Auroville, builder and community
  is same self dependency for housing
  construction
• Very organic in nature
