The Kochubey mansion by the famous German architect Harald von Bosse is a fine example of St. Petersburg architecture of the second half of the 19th century.
Prince Kochubey commissioned Bosse to re-structure the existing buildings on the purchased plot of land. The reconstruction project was completed in 1857. The architect undertook his task according to the aesthetic requirements of the time. The mansion was built in the Florentine style popular at the time and came to be known as the House with the Moors.
