A pavilion was built in the garden by the order of Naser ed Din Shah of the same dynasty, which was originally referred to as Niavaran House, and was later renamed Saheb Qaranie House. The pavilion of Ahmad Shah Qajar was built in the late Qajar period.
During the reign of the Pahlavi Dynasty, a modern built mansion named Niavaran House was built for the imperial family of Mohammad Reza Pahlavi. All of the peripheral buildings of the Saheb Qaranie House, with the exception of the Ahmad Shahi Pavilion, were demolished, and the buildings and structures of the present-day complex were built to the north of the Saheb Qaranie House. In the Pahlavi period, the Ahmad Shahi Pavilion served as an exhibition area for the presents from world leaders to the Iranian monarchs.
