Rana dynasty
Singha Durbar was built by Shumsher immediately after accession to the post of Prime Minister. It was initially a small private residence but grew bigger during the construction. Immediately after construction, Shumsher sold this property to the Government of Nepal for 20 million Nepali rupees as the official residence of Prime minister. After his death in 1929, it was used as the official residence of prime ministers of Rana dynasty except Padma Shumsher JBR, who lived in his own Bishalnagar Durbar. The last Rana Prime minister to occupy Singha Durbar was Mohan Shumsher JBR. Even after the fall of Rana Dynasty in 1951, Mohan used this place, but in 1953 he was ordered by His Majesty's Government to leave the palace which became National Property.
