The head of the railway announced that the lawyer who won this case would receive Dombrovsky's mansion as a gift.

The Rostov lawyer Apollon Petrovich Petrov undertook to defend the interests of the railway, and won the legal case.

After the Great Patriotic War, the building was transferred to the regional department of affairs of construction and architecture.

During this period, an attic was added to the mansard, a concrete staircase was built, and a wooden terrace and a marble fountain in the garden were dismantled.

The Petrov Mansion is built in an eclectic style; its design combines baroque, classical and renaissance motifs.

The frieze above the windows is richly decorated with stucco elements: female heads, griffins, cartouches, and floral ornaments.
