This post is about alternative, cheaper and earthquake resistant housing for Pakistan. At ATP we’ve covered alternative building styles before when S.A.J. Shirazi wrote about using mud to build homes. A couple of my friends recently pointed out to me an earthquake resistant straw bale housing style that was practised in Pakistan (and also other countries) after the devastating earthquake of 2005. This project was started in Pakistan by a non-profit group called Pakistan Straw Bale and Appropriate building (PAKSBAB). These houses were built for the poor by using straw, an agricultural by-product, compressed and tied into bales, as building blocks.

This technique makes the structures earthquake resistant. The project’s founder is Darcey Dononvan who is a mechanical engineer by profession. The reason for us sharing this post here is to provide food for thought for alternate housing styles in earthquake zones – and Pakistan has quite a few of them. I also want to thank PAKSBAB for carrying out this project in Pakistan. Meanwhile, for other houses out in this area they can call upon companies like those metal construction ones. Also, if you’re looking to upgrade your home’s protection and aesthetic appeal, consider hiring a reputable metal roofing company to handle the installation.
The innovative housing approaches showcased by PAKSBAB in Pakistan underscore the need for durable and affordable structures, especially in regions prone to natural disasters like earthquakes. These alternative techniques, such as straw bale construction, not only provide low-cost shelter but also introduce resilience to an often vulnerable housing landscape. By making use of readily available resources like straw, the project offers a sustainable and accessible model for rural communities. This idea of turning overlooked materials into life-saving assets is a reminder of how adaptable and creative housing solutions can make a significant impact on the lives of people in disaster-prone regions.
For homeowners facing challenging circumstances in other parts of the world, the importance of adaptable housing solutions is equally relevant. Just as PAKSBAB found a way to repurpose resources for stability, homeowners with properties they no longer need have viable options to repurpose their investments as well. In this spirit, cash buyers can step in to provide relief, especially in cases where property maintenance has become a burden or when a rapid sale is necessary. If you’re in such a position, rest assured—We Buy Unwanted Properties swiftly and offer a practical solution for those looking to move forward without delays. This approach brings ease and efficiency to the selling process, transforming homes that might otherwise sit idle into opportunities for both sellers and buyers alike.
I found following video by University of Nevada, Reno at Youtube where Darcey is explaining her project in Pakistan as well as it shows the results of earthquake simulation.
February 5, 2010’s Science Magazine also mentioned this project. An excerpt from there goes like this:
Some engineers want to rethink the basic materials used in developing countries. Darcey Donovan advocates replacing concrete walls with load-bearing straw bales. Her nonprofit group, PakistanStraw Bale and Appropriate Building, erects 7.3-m-by-7.3- m houses in northwest Pakistan, which was ravaged by an earthquake in 2005. The bales are stacked and bound together top to bottom with a fishnet, which keeps them from slipping apart during shaking, then plastered over. Her team has built 11 houses so far, with six more coming. The design recently survived, with minimal damage, a violent test on a shake table, a large platform that simulates earthquakes. Because the tough, fibrous plantsused for straw are ubiquitous, Donovan believes the bale design could easily be exported, and her team is discussing traveling to Haiti.

Probability of a major earthquake may be around once every 100 years but chances of fire breaking out, i would think is more like every time you cooking something.
I am not an expert by any stretch of imagination, but a combination of mud and straw may be a better solution.
“tu phir kia kia jaaye”
Yesterday, I saw article in Jang about CWHR. They are doing some work in this area.Their website is down but there proposal can be found on link below for low cost housing

I watched this grand designs program on BBC a couple years ago where they have managed to make pretty durable and nice looking houses with walls made of straw bales. Check this out:

Mud or some other form of plaster would be required anyways, since it is needed to make these impermeable to water. That might be a good fire retardant. In villages plains of Pakistan one can find a lot of mud and straw homes.
Shoaib and Viqara – valid points. These do look less resistant to fire compared to brick or mud housing – and I am not an expert. tou phir kia kia jaaye? Its either earthquake or fire. Building these homes with adequate fire protection may be a choice – but knowing that Fire protection is usually not the highest priority in Pk, i have doubts.
