The Potocki Palace (only testified, not built), Shidlovsky, and Vorontsov Palaces in Odessa were built to his designs, as was the Czarnomski Palace near Bershad (1817). The latter is famed for its uncanny resemblance to the White House. The Potemkin Stairs, Boffo's most ambitious undertaking, was modeled on the earlier Depaldo Stairs, designed by him for the town of Taganrog in 1823. It was Boffo who conceived a 22-metre memorial column for the Kagul battlefield. He also built the Londonskaya Hotel building in 1826–28 as a private residence. The architect died in 1867 and he was buried in Odessa.
