What's the story behind the construction of Dixit Wada in Shirdi? I heard Dixit built it, but how did it come about?

The story of Dixit Wada's construction is detailed in Chapter 4. The idea began in December 1909 when Kaka Saheb Dixit, after his second visit to Sai Baba, first thought of building a tin roof to provide convenient accommodation for pilgrims. This initial thought later evolved into a firm decision to build a more substantial stone Wada. The following year, after securing Baba's approval, the foundation stone was laid on December 10th, 1910, which was considered a very auspicious time. The text also notes that, even without being called, Dixit's brothers arrived for the ceremony on that very day.
