Participants are expected to arrive by 5 pm on 25th Nov or earlier.



This will be the most ambitious project at Sapna Ranch to date. It culminates all the combined learning of Eco-Construction I have had over the years. Everything outlined here has already been built at an individual level. Now we are going to build a full new set altogether. Hence the word Confluence. What we are going to build is a first version of the the pod/home of EBHLE. This will be a significant milestone event on EBHLE’s and hopefully your timeline.

Age group: 4-94, adults, parents, grandparents and kids all included.

The main activities are:

  • Geo-thermal (25-30 Nov)
    • Digging, laying pipes, filling soil back
    • Sapna Ranch has one of the few Geo-thermals in all of India. Don’t miss this opportunity.
  • Geodesic Dome (25 Nov – 4th Jan)
    • This is a 36 ft diameter, 3 story/level dome
    • Approximately 2,200 sq ft of living space

Expectation from Attendees

  • Good sense of humour
  • Come with zero expectations
  • Open mind for learning

Fees and Participation

The total expected cost for all that we are going to build during this Confluence is about Rs. 20 lakhs (US$ 30,000)

There are people with less than half the items on the agenda who charge upwards of Rs. 10,000 per week. I want to share our learning with as many people as possible. That is why the cost of the Confluence is being kept to a minimal amount of Rs. 4,000 per week. This cost covers basic accommodation and all meals (breakfast, lunch, dinner, tea/coffee, juices and snacks) 

As a gesture of practicing gift culture, we would like to accommodate everyone in this workshop : those who can afford and those who cannot afford it. However, we need your help in this humanitarian endeavor. We are keeping 4 categories for participants:

  • I will pay Rs. 4,000 per person per week
  • I will pay Rs.6,000 per person, which includes Rs. 4,000 for myself and Rs.2,000 to partially support one more person
  • I will pay Rs. 8,000 per person, which includes Rs. 4,000 for myself and Rs. 4,000 to fully support one more person
  • I am unable to fund my participation : Please contact us, and we will make efforts to accommodate you.

Payment can be made in advance via online wire transfer, click here for account details. Or you can pay by cash or cheque on arriving at the ranch.

Disclaimer : All registrations will be approved on a first-come first-serve basis. Ability to pay will not have any weightage in that decision making.

We are limiting number of participants to 45. In the previous summer workshop, we got over 70 registrations and as a special gesture, we accommodated 50 and the rest had to be declined. So please register at the earliest.



Please register separately for each person/child participating. Please send an email to with the exact dates for which you will be attending the Confluence.
