Can you describe the process and timeline for the construction of the Dixit Wada?

The idea for the Dixit Wada began after Kakasaheb Dixit's first darshan of Sai in November 1909. As recounted in chapter 4, when he returned for a second visit in December of the same year, he first had the thought to build a tin roof for the convenience of pilgrims. This idea later evolved into a firm decision to build a proper Wada. The following year, after receiving Baba's approval, the foundation stone was laid on December 9th, which was considered an auspicious time.
