The house of merchant Yevgeny Mikhailovich Dyakov is a monument of history and architecture from the early 20th century. E.M. Dyakov, a first guild merchant, was engaged in grain trading and livestock farming. He built his estate in 1903.

After 1917, the house was transferred to municipal ownership and was used for various purposes: it housed the Cheka, a kindergarten, the Soviet House, the city committee, as well as the regional Komsomol committee, the political education house, and the department of public education. In 1983, the mansion was recognized as a regional architectural monument. In 1995, the administration of Balashov transferred it to the culture department, and in February 1996, a branch of the Balashov local history museum opened here. The house is included in the list of objects of historical and cultural value in the Saratov region.

The manor house is a wooden single-story building with a basement, covering an area of 204 square meters. The foundation is made of stone, the walls are made of logs, clad in "herringbone" pattern, and adorned with carvings. The architecture of the house is eclectic, with a predominance of Eastern motifs: Arabic patterns on window frames, ornamentation on corner pilasters, and downspouts shaped like winged dragons. Elements of Russian architecture are encountered less frequently.

The mansion has eleven rooms, five of which are residential. Dyakov's belongings have not survived, but the interior decoration remains in good condition. The ceilings are decorated with plaster moldings, and the cornices, corner patterns, and rosettes for light fixtures are preserved. The ceilings are covered with wallpaper but painted over with oil paint, except for the bedroom, and require restoration.

The walls in the living area are wallpapered. In the dining room, study, and corridor, the lower part of the walls is covered with panels made of embossed cardboard, while the upper part is covered with embossed paper wallpaper featuring a floral pattern. In the living room, bedroom, and grand hall, fabric wallpaper and plaster moldings are used. All materials are in good condition, with minor damage. In the study, the walls are painted with oil paint.

The house retains fireplace stoves with glazed ceramic tiles from the Finnish factory "Abo." The floors in the living rooms are parquet, made from three to five types of wood, with unique patterns in each room.

Exhibitions are held in the house: "Russian Classicism" featuring reproductions of paintings by Russian classicist artists of the 17th-18th centuries and "The Flour is Ground, the Work is Done," dedicated to the history of the Balashov grain processing plant. Museum staff conduct tours of the mansion and thematic walks around Balashov.

The mansion retains original windows and doors with fittings. By the early 20th century, the house had plumbing, a closet, a bathroom, electricity, and a telephone.

Currently, the mansion houses a branch of the local history museum, while the rest of the estate is not in use. The territory retains a stone stable in poor condition and fragments of a brick fence. Restoration is needed not only for the house but for the entire estate.
