By the mid-19th century, Rostov-on-Don was a significant trading center in the south of the Russian Empire, home to people of various nationalities. The city's history is closely intertwined with German brewers who settled here and became part of the Don history. One testament to the German presence is the house of Oskar Baziner, the owner of a large brewery in Novocherkassk, which he inherited from his father, August Baziner.

The exact year of construction of the estate in Rostov is unknown. Previously, these two neighboring buildings belonged to Pyotr Timofeevich Kramarenko, but in 1911, they were purchased by Oskar Baziner for 7,300 rubles (4,000 rubles for the house at Dmitrievskaya, 12, and 3,300 rubles for the house at Nikolskaya).

In 1914, these buildings housed a beer warehouse for Baziner's brewery, and the manager of the brewery, Heinrich Mann, the grandson of the founder of German breweries in the Don, lived here. Under the new owner, the estate expanded and became worth 23,600 rubles, acquiring a triple address and occupying an entire block.

With the onset of World War I, the situation for German merchants worsened due to distrust towards German firms, through which Germany could conduct industrial espionage. Although many Russian Germans were patriots of Russia, the war undermined trust, and in 1916, the Baziner-Mann-Bille families decided to leave Russia. Part of the family moved to Germany, while others went to Persia.

Oskar Baziner's estate in Rostov passed to the city and became a communal house after the arrival of Soviet power. Today, the building continues to deteriorate but still retains a glimpse of its former beauty. Within its walls, one can find fragments of the decor from those years, antique cast-iron bathtubs on bird legs, and other echoes of the past.
