The estate consisted of a central building with about farmland and numerous additional farms.

Gottlieb Ernst Rüchardt acquired the Rittergut Schackenhof on 15 July 1814. He operated the agricultural estate, followed by his son August Adolf Eduard Rüchardt and grandson Adolf Theophil Eduard Rüchardt. Grandson Georg Konrad Lebrecht Rüchardt, who had not inherited the estate, had gone to Moscow in about 1880 and married into the trading company Wogau & Co, where he became a director and co-owner. In about 1900 he took over Schackenhof and expanded the main building to the palace that remains today. The estate was run by an administrative director and served the family until 1905 as one of their summer residences.
