The estate in Gubarevo, preserved to this day, is located in the southern part of the village and belonged to the noble family of Losyevs. In 1780, the manor house was still wooden. In the early 19th century, the main figure of the estate became Guard Lieutenant Ivan Ivanovich Losyev, who was born around 1790 and died in 1841, being buried in the same village.

Unfortunately, very little information about the estate life of the Losyevs has survived. An exception is the portrait of I.I. Losyev, which is kept in the I.N. Kramskoy Regional Art Museum.

It was during Ivan Ivanovich Losyev's time, and possibly under his parents, that a magnificent two-story brick house in the Empire style was built in the early 19th century. It faced the picturesque floodplain of the Veduga River, and its southwest facade embodied all the splendor of Russian noble life and mature classicism. The four-column portico of the second floor rested on an elegant arcade supporting the balcony, and was topped with a triangular pediment. The architecture of the house resembles the house of the Tulin family in Voronezh, but the Losyev estate is more free and imposing, with a wide arch in the triangular pediment. In the center of the composition, above the balcony, there is a large semicircular window. In front of the portico was an arch in the form of a grotto, likely made of natural stone from the Chernysheva Mountain. Two staircases, ascending through the arch, connected into one flight leading to the balcony. The park area connected nature and architecture: a stone grotto was arranged on the plateau, and the park descended to the river in terraces, leaving large stones in the landscape. The plateau was decorated with linden trees, shrubs, and flower beds.

A plan of Gubarevo, found in the RGADA, dates back to 1856 and shows the estate in its current location with a brick house and outbuildings. At that time, the owners were no longer the Losyevs, but the Somovs, heirs of Lieutenant Mikhail Nikolaevich Somov.

Afanasy Nikolaevich Somov, born in 1823 and died in 1899, left a mark in history, with the Somovo railway station in Voronezh named in his honor. In 1859 and 1868, he was the provincial leader of the nobility and the first chairman of the provincial zemstvo administration. The estate has preserved the layout and buildings of the 19th century. The entrance road, adorned with lilacs, leads from the village church and transforms into the main alley. On the right is the ceremonial area with the main house and park, while on the left is the economic area with two outbuildings and a garden.

After the Civil War, the estate housed an agricultural station. Judging by photographs from the 1920s-1930s, the main house retained its architectural splendor before the war. However, after the war, when a school was placed in the house and it underwent multiple repairs, the mansion lost its portico with a balcony. The courtyard facade has survived better, highlighted by pilasters and a triangular pediment. The main facade retains pilasters and some details, including an archivolt marking the place of a destroyed window. These remnants of decor emphasize the negligence of the repair workers and evoke a desire to restore the building. Since 1994, it has been under state protection, and since 1995, it has had the status of a federal architectural monument.

Hopes for a full restoration of the house and estate are dwindling. In 2015-2016, the school building in Gubarevo suffered the same fate as the estate schools in Ternovoe and Razdolye. The school is no more. The new owners took care of the property’s preservation, replacing the roof and fencing the area. However, builders again damaged the decor by covering the upper parts of the cornices with roofing. Nevertheless, it is good that the monument has found a purpose and will not turn into ruins.
