What details does the text provide about the construction of Sathe's Wada?

The provided source chunks from Chapter 18 do not offer any details about the construction of Sathe's Wada. The Wada is mentioned frequently but only as the location for a specific spiritual activity. Chapter 18 establishes that the daily readings of sacred texts like the Jnaneshwari and Nath Bhagawat, conducted by Bapusaheb Jog, took place there. Baba would often direct devotees who came to see him at the Masjid to go to the Wada to listen. The focus is entirely on the events happening within the Wada, not on its physical structure or history.
