At the confluence of the Okker River and the Ohta River, remnants of an ancient estate known as Utkin's Dacha have been preserved. Before the founding of St. Petersburg, the plot belonged to Swedish Colonel Okker, after whom the local river is named. Later, it was owned by the nobleman S. Nelydinsky-Meletskoy, and then by Count A. I. Ushakov, a general and head of the secret office.

In the mid-18th century, the plot passed to the Poltoratsky family. Agafokleya Alexandrovna and Mark Fyodorovich Poltoratsky, who lived in Tver Province, received it as a reward for Mark Fyodorovich's participation in opera productions. He was the director of the Court Singing Chapel and the first Russian singer to perform in Italian opera. Their daughter, Agafokleya Sukhareva, managed the Okker estate and also owned the neighboring plot. Another daughter, Elizaveta, married A. N. Olenin. Their daughter Anna Olenina was a guest at A. M. Sukhareva's.

The manor house of the Okker estate was built in the 1790s according to a design by N. A. Lvov. The service building appeared in the 1820s-1830s, but its author is unknown. The estate included ice houses, cellars, stables, barns, greenhouses, and an orchard with apple and cherry trees. The estate's produce was sold. A landscaped garden stretched along the Ohta River to the Zhervonka estate.

The Poltoratskys also owned the neighboring estate of Kosaya Gora with a winery and livestock yard. In the 1810s, they decided to sell the estate. In 1814, an advertisement appeared in the 'St. Petersburg Vedomosti' about the sale of the Okker estate, requesting inquiries to A. M. Sukhareva. On December 21, 1828, an agreement was made to sell the property to Princess Zinaida Petrovna Shakhovskaya.

After the death of her husband, Prince A. Y. Shakhovsky, Zinaida Petrovna married the justice of the peace Vasily Ivanovich Utkin, whose surname became associated with the estate. Zinaida Petrovna died in 1870, bequeathing the estate to the Imperial Society for the Care of the Poor, but it was to pass into its management only after the death of V. I. Utkin.

From 1870 until the death of V. I. Utkin (presumably in 1872), the estate fell into decline as it had no owner. It was impossible to quickly transfer it to the Imperial Society due to the conditions of the princess's will. In 1873, the Ohta Mariinsky almshouse for the incurably ill and disabled opened here in the presence of Emperor Alexander II. The condition regarding Utkin's Dacha was fulfilled by 1881, and the society organized a children's shelter here, which shared premises with the almshouse until 1882.

In 1904, Utkin's Dacha was leased for a city almshouse for the mentally ill. In the 1920s, the manor house belonged to the Health Commissariat, housing the Malo-Ohtinskoye branch of the 2nd Psychiatric Hospital.

On May 29, 1920, architect Postnikov examined the estate. Inside, frescoes by D. Scotti, a plaster cornice, and a gilded frieze, as well as ceiling paintings, were preserved. In 1933, during repairs, the frescoes in the main house were destroyed or whitewashed, and the ceiling in the service wing was covered with plywood. In 1936, part of the buildings was repurposed into apartments, housing the 176th 'Children's Hearth' of the Volodarsky District Housing Union.
