Rubble Bag Houses

Concrete rubble from collapsed buildings is a huge problem in Haiti. It is blocking roads and hindering reconstruction. Instead of spending millions of dollars trucking the rubble away and disposing of it, why not use it to build affordable housing?

Disaster Resistant Earthbag Housing

One of the greatest needs in the world is disaster resistant housing – houses that can hold up against hurricanes, earthquakes and other natural disasters. Properly designed structures can save millions of lives and millions of structures every year.

Recycled Plastic Block Houses

Turn low value plastic trash into valuable building blocks with a $300 homemade press. Free plans for a hand operated press are available. A mechanized version could be made by converting a log splitter.

Parallel Chord Pallet Trusses

If you have access to small diameter trees and wood pallets, and live in an area not restricted by building codes, then this truss design is one good low cost roof option. If you do all the work yourself, these trusses are virtually free.

Key Considerations for Building Affordable Housing

Building housing projects in developing regions is extremely rewarding, but also quite challenging. It’s prudent to draw ideas from as many resources as possible to improve the process. The following guidelines have proven effective.

Reinforced Earthbag Specifications

Precision Engineering has generously provided drawings and specifications for building earthbag structures in seismic areas to meet code. The documents have been combined into one 6-page PDF and are now available online.

Why is There an Energy Crisis?

A BIG issue in everyone’s lives today is increasing fuel costs. The seriousness and scope of our energy problems calls for an all-out effort for sustainable solutions, starting as soon as possible.

Earth Building in Thailand

I had heard there are thousands of new earthen houses in Thailand. That really amazed me, so I set out to learn the details about the modern earth building movement in Thailand.

Low-fired Brick

Low-fired brick is a very sustainable building material with low embodied energy. They are made with locally procured clay and fired with rice hulls, a by-product of growing rice. Brickyards are located near urban areas to minimize transport costs.

Double Pole Roofs

This article describes an alternative roof design for those building in areas without building codes. A little extra effort working with poles will reward you with a stunningly beautiful wood ceiling and superinsulated roof at very reasonable cost.

Mortgage Mess Was Avoidable

The thousands of families who have built affordable homes, cash up front, made of earthbags, straw bales, cordwood, cob and rammed tires are not in danger of losing their homes in the current mortgage crisis.

Small Diameter Roundwood Trusses

The roundwood truss system described here enables DIYers to build their own trusses at very low cost. You can gather truckloads of poles from national forests, enough for several small houses, for the cost of one $25 firewood permit.

Earthbag Building: The Next Big Thing?

Earthbag building has just received engineering approval. This is probably the greatest news ever for earthbag building. With engineer-approved plans, we see unlimited potential for earthbag building for homes, shops, schools, you name it.

Insulated Earthbag/Geotextile Basement Walls

The earthbag/geotextile basement wall system described here has excellent potential to save on initial construction costs and long-term energy costs. No concrete is used. The same principles have been used to build retaining walls for decades.

The Case for Using Sustainable Building Materials

Recently, I had an epiphany in a building supply center. Even though I’ve been in the building trades for over 35 years and made countless trips to purchase building supplies, this trip was different.
