The complex consists of several buildings. At the corner of the block is the gymnasium, built at the turn of the 19th and 20th centuries. Its first floor extends west along Sovetskaya Street, forming an L-shaped service wing that borders the courtyard on the west side. To the south of the main building is a two-story house from the first half of the 19th century, connected to the gymnasium by a gate. The entrance is from the gymnasium courtyard.

The gymnasium was founded in 1908 by Serafima Alexandrovna Tovarova with the active support of her husband, physics and natural sciences teacher Konstantin Vasilyevich Tovarov, as a second-class male educational institution. Funding was provided by the founders, the city duma, and the district zemstvo. In exchange for subsidies from the city authorities, some students were exempted from tuition fees.

By 1912, the gymnasium received the status of a first-class educational institution, and in 1914, with the opening of the seventh grade, it became a classical gymnasium with the rights of government educational institutions.

Notable educators such as L.V. Sorokin, K.V. Tovarov, D.K. Ivanov, I.A. Shvedov, N.V. Glazunov, G.F. Dolomanova, V.V. Komarov, A.F. Sykoра, F.I. Yerokhin, and others taught at the gymnasium.

During World War I, teachers and students actively participated in the public life of the city, organizing charitable concerts and performances in support of the wounded. After the February Revolution in March-April 1917, lectures on current events were held here.

The gymnasium is a two-story brick building, with an eastern facade facing Dubrovin Street and a northern one facing Sovetskaya Street. From the courtyard side, the building has a complex volumetric composition. The street facades are adorned with small risalits: a central three-axis one on the east and two-axis side ones on the north.

The decorative design of the facades, executed in an eclectic style, uses motifs of classicism. A high plinth with panels, a window sill, an inter-floor cornice, and rusticated strips create horizontal divisions on the first floor. The windows here are rectangular, in framed casings with ears. The second floor is decorated with a bracketed window sill above the panels. Large arched windows alternate with paired half-columns supporting a bracketed entablature. The central axis of the main eastern facade is highlighted by a small projection with bundles of half-columns. The risalit is crowned with a stepped attic with a rounded finish. The attic is decorated with panels and round openings.

Inside the building on the first floor are a large vestibule (the original entrance from the east is closed), a corridor along the southern facade (entrance from the courtyard), and two classrooms in the eastern and northern parts. A two-flight staircase leads to the second floor, where a corridor connects the stairwell with a square hall in the eastern part. The hall has doors leading to five surrounding rooms. The room corresponding to the risalit of the eastern facade has two corner tiled stoves.

The service wing, a one-story brick building, adjoins the western wall of the gymnasium. Its decorative design is extremely simple, with a finishing cornice, pilasters, and rectangular windows. The internal space is divided by transverse walls into a series of adjacent rooms, likely workshops and storages.

A two-story brick house, built before 1840, faces its main facade towards Dubrovin Street. It has a rectangular plan and extends deep into the plot. The concise decor of the facades includes cornices and simple inter-floor elements. The windows of the first floor are rectangular, while those of the second have arched lintels.
