    Namaste Poonam,

    Firstly the amount of money you can save in constructing your home by learning and applying this method is very much higher than how much you are investing for this course.
    We are working in barter system with our projects, the money to run the organaisation comes through teaching at these workshops only. So by attending our workshop, you will be contributing to our future research and studies, along with your own learning.
    We had two common man workshops, 1 day plaster workshop and 4 day farmer’s natural building workshop held in april & may for people who could not invest more money in learning, you can attend these workshops next time.
    We appreciate your thirst in learning natural building.
