The architectural design of the building is executed in an eclectic style with elements of neo-baroque. The main facade on Soviet Street features a symmetrical composition with five parts and nine axes. The side and central risalits of the facade are adorned with decorative parapet walls with vases. Door openings are located at the first floor level. The first floor is distinguished by horizontal rustication and large arched window openings with framing and a keystone.

The windows on the second floor are smaller, rectangular, with framing featuring rounded corners and a rectangular architrave. Between the second-floor windows are pilasters on fluted pedestals. A wide frieze with geometric decor is separated by a cornice belt. Plaster decor in the form of rosettes adorns the pilasters, their bases and capitals, as well as the window sill of the second floor. The inter-floor cornice is decorated with guttae, while the crowning cornice features small blocks and brackets. The windows of the courtyard facade have semicircular lintels and profiled architraves.

The building is located at the corner of Soviet Street and Proletarian Lane, characterized by strict proportions and belonging to the eclectic style. Rusticated pilasters divide the main facade into two parts, while the facade on Proletarian Lane is divided into three. This division is likely related to the development of the estate's construction. There are two door openings on Soviet Street. The window openings on the first floor are rectangular, with profiled framing and a three-part keystone. On the second floor, the windows are also rectangular, with a decorative keystone and empire-style garlands. A rectangular architrave is placed above the keystone. Flat pilasters are located in the intercolumniations. Large blocks are positioned at the base of the frieze, while small ones are in the cornice. A parapet post has been preserved at the corner of the building.

The house was built in the second half of the 19th century. There is a late addition on the courtyard side. The history of the building is connected with P.Y. Soplyakov, an honorary citizen of Syzran and property owner. He owned shops on Bolshaya Street (now Soviet), including N.S. Belousov's manufacturing shop and Meyer’s gold and silver shop. The second floor was rented by a mutual credit bank founded in 1905. It is likely that Belousov's goods were popular, as the architectural monument bears his name.

After the revolution, the building was nationalized and used as a shop. During the Great Patriotic War, it housed a hospital, and at that time, the addition appeared. In the 1950s, the Central Savings Bank was located on the second floor. From the 1970s, the first floor was occupied by a bookstore and a society of hunters and fishermen.
