Palace of the Four Winds reconstructed the palace in the rococo style, probably to a design by Johann Sigmund Deybel. The magnificent sculptures of the Four Winds ("Notus", "Boreas", "Zephyrus" and "Eurus") atop the fence posts date from that period. The artist is unknown, but probably also participated in decorating the Saxon Garden. In 1769–71 the palace was rebuilt by Szymon Bogumił Zug for Piotr Tepper. The right wing was widened, and a new annex was erected adjacent to "ulica Długa", with an early-classicist front elevation. In 1801 the palace was purchased at auction by Karol Fryderyk Dückert. Until 1891 it belonged to his heirs.
