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.

    Hii friends

    This is Hariharakarthikeyan from Trichy
    Actually i’m civil engineer and i’m very much interested in natural building and i would like to construct my own house using natural resources

  38. Sorry Neelima presently our courses are held in our campus in Tiruvannamalai, Tamilnadu. Its worth a visit in south India under the foot of Arunachala.

  39. Namaste,
    Difference between 10 day workshop & 15 day workshop.
    In 10 day workshop, every aspect of Natural Building from Foundation, Wall, Finishes, Flooring and Roofing is covered. It is a comprehensive course on all topics needed to build a home.
    In 15 day Workshop, different kind of Natural finishes – Mud Plaster, Mud + Lime Plaster, traditional Rajasthani Lime Plasters, Natural Colours, Plant & Animal Admixtures, Flooring etc is covered. Other parts of building like Walls, Roof, Foundation etc is not covered in this course.

    Please look into the course details of both workshop.

  40. Is the topics covered in 10 days Natural Building Workshop, will it be there in 15 days Long Course in Natural Finishes & Flooring October 2019?

  41. 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.

  42. Beyond my budget.. But I wish it could be available for interested low budget candidates like me.
