toiletAs part of our ongoing commitment to the rural Bangladesh, we organize workshops to build toilets. This volunteer program has seen a surge of interest among architects, students and engineers over the years. This is a non profit venture and volunteer based system.

According to WHO, more than thirty million people in rural Bangladesh does not have access to proper sanitation. We select the families who does not have the means to make a toilet of their own, let alone hire architects or engineers. We talk to the families and device a participatory approach. Meaning, the toilet is not a gift. They have to pay at least 20% of the cost and give labor. We pay the rest and the volunteers put it together. A clear manual is usually provided and within two days, we manage to make four-five toilets.

This has been a successful program so far. It was even featured by the commonwealth association of architects. Here are more information:

Earth Architecture Training:

Earth Architecture is a worldwide phenomenon and making resurgence in 21st century. There are many ways to build a house with earth. But among them Compressed Earth Block (CEB) technology is the most efficient ways to build houses with earth.

Plastic cement block technology is environmentally sustainable method that is gaining a lot of popularity. It also helps to clear plastic waste from the environment.

Both of these construction technologies are fireproof, sound proof, bug proof, bulletproof, breathable, mould proof, nontoxic, low cost, low maintenance, structurally sound, earthquake resistant, and provide amazing insulations. The high insulation of earth blocks and cement blocks makes it very comfortable to live in during high heat of summer or freezing cold of winter.

We can provide excellent service for your project.
