Since I am already in the middle of construction of a space, it would be best for me to understand natural building soon, hence I want to participate in the December workshop.

    Hello Thannal Team,

    I have two kids aged (5 & 9 yrs) whom i would like to get along for the February workshop. However, won’t it affect my concentration and learning ability or are your programs designed in such a way that they will get to learn and at the same time , me too? I don’t even know how to frame this question, but i had to put my concerns here, since your phone number is not available. Also, which is the nearest station to your venue. I shall be coming from Mumbai. And what should be the total approximate cost apart from the course fees? What is the best and cheapest lodging available and again best and cheapest way to reach course venue everyday? Kindly call me on 9920887469 as i would prefer discussing this on phone instead of comments section. It would also be easier for me to book for the course, if I am aware of all the above asked details. With Regards, Ar Pratiksha

    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.
