The first owner of the Primorskaya estate, consisting of three Peter the Great plots, was Count Gavriil Ivanovich Golovkin, the first chancellor of the Russian Empire since 1709 and a companion of Peter I. From 1719 to 1734, owning lands on the southern shore of the Gulf of Finland, Golovkin built a stone house and arranged the estate with a pond, a livestock yard, and other outbuildings. He was often visited by A.D. Menshikov, who, for example, spent an hour there on July 1, 1716, and last visited the estate on August 31, 1727, shortly before his downfall. After Gavriil Ivanovich's death, the estate was owned by his widow Domna Matveyevna and grandson Count Gavriil Ivanovich.

In 1745, under Domna Andreevna, the estate, in addition to the main house complex with nine rooms, a kitchen, a bathhouse, and other buildings, developed an extensive economy. There were a livestock yard, 7 desyatinas of arable land, a barn, a granary, and a shop by the road.

Between 1785 and 1793, the estate passed to retired ensign of the Horse Guards, Ivan Ivanovich Korsakov, the district leader of the nobility in Novgorod. After his death, his widow Agafya Grigoryevna, born Konovitsyna, became the owner, followed by their son Nikita Ivanovich Korsakov. In 1801, he married Princess Vera Ionovna Dondykova, whose mother Maria Vasilievna also came from the Korsakov family, and whose father, Prince Iona Fyodorovich Dondykov, was a brigadier and officer of the Preobrazhensky Regiment.

On July 15, 1802, at the request of his mother-in-law M.V. Dondykova, Nikita Ivanovich received permission to be called Prince Dondykov-Korsakov to prevent the interruption of the lineage. He managed the ancestral Pskov estate, the village of Polonaya, the locality of Romanovo, and later the Roshchinskoye estate. He had a passion for rarities, and his home resembled a museum with a picture gallery and a collection of Pompeian and Etruscan vases and mosaics. He had a single daughter, Maria Nikitichna.

In 1857, the Roshchinskoye estate passed to Maria Nikitichna. The last representative of the family to own Roshchinskoye was her son Vladimir Mikhailovich Dondykov-Korsakov.

The garden of the estate was first clearly marked on the 1817 plan. It had a square shape with cross-shaped alleys, stretching from the main building to the ravine in the west. Along the northern boundary of the garden were the estate buildings, and the existing ponds were marked on the plan.

The architectural complex of the estate developed westward from the main house. Nearby was a one-story wing with a mezzanine in the style of English Gothic, possibly serving as a kitchen. Further on were an orchard, greenhouses, and a farm. In the ravine at the western boundary of the estate was the Swiss dacha, built in the 1840s-1850s, surrounded by a miniature landscape park. In the early 20th century, a small pond was created with the help of a dam, and a stone icehouse was built. On an island in one of the ponds, the beloved dogs of the owners were buried.

In 1887, Vladimir Mikhailovich Dondykov-Korsakov sold the estate to Count Platon Alexandrovich Zubov, retaining only a small eastern part. The new owner named the estate Otrada. For the Zubovs, the estate was not only a summer retreat. A fire brigade was organized here, participating in extinguishing fires in Oranienbaum and nearby villages. Under the Zubovs, the main house was reconstructed and painted white, earning the name 'White Dacha.'

According to the memories of Count G.G. Karlov, the estate was surrounded by mighty fir trees that descended to the sea. The house was white, in the style of Empire or Biedermeier, and very cozy.

In 1919, it housed a branch of the Petrograd Agricultural School. Currently, the estate is in a deplorable state.
