The history of the Royal Oasis begins in the 1870s when Banesinhji erected a single-storey bungalow in colonial-style architecture for resting and named it Garden House.
[1] After Banesinhji, his son and successor, Amarsinhji continued using it for the same purpose and would host his guests there.
[1] In 1917, when Amarsinhji's daughter married Purna Chandra Bhanj Deo, the Maharaja of Mayurbhanj, he hosted them there and named it Purna Chandra Bhawan after his son-in-law.
[3] In the 1930s, Amarsinhji commissioned the Chief Engineer of Wankaner State to build an extension to the original building, which consisted of two large suites, four other bedrooms, and additional rooms.
[1] It is now a two-storey block in cream and white stucco with Corinthian plaster details.
