The enterprising and wealthy capitalist Tretyakov, engaged in distilling, effectively seized the large village of Sudislavl and then expanded his activities to Kostroma, building income houses there. The first building on Simanovsky Street was erected by him at the beginning of our century, and the second, corner building, at the end of the last. These structures became the most significant in Kostroma from the mid-19th century until the October Revolution. Both buildings were constructed well, but their architectural and artistic merits leave much to be desired.

The facades and interiors are overloaded with stucco details, characteristic of merchants' grandeur. In the second building, before the revolution, there were shops, a bank, and various offices, and during the Civil War, the provincial military commissariat.

The first provincial military commissar in Kostroma was Filatov, who soon went to the front. M.F. Bukshtynovich played a significant role in the military commissariat, later becoming a general and an important worker in the General Staff. The provincial military commissariat was actively involved in creating and sending units of the Red Army against Kolchak and Denikin, as well as suppressing White Guard uprisings in the region. V. Frunze, commander of the Yaroslavl military district, often visited here. Previously, this building housed the editorial offices of the regional newspapers 'Severnaya Pravda', the first issue of which was published in 1907, and 'Molodoy Leshtnets', published since 1956.

In the corner house, a private music school run by Sumarokova operated since 1900, as well as a treasury chamber that managed finances and state properties in the province. Today, the building has been returned to music educational institutions, housing a music college and a children's music school.

Previously, on the site of Tretyakov's houses stood a small building where the family of the teacher of the Kostroma gymnasium V.V. Chizhov lived. Here grew Fedor Vasilyevich Chizhov, an outstanding public figure and educator.

Fedor Vasilyevich's father was not favored by the authorities due to his restless character and often faced persecution, causing the large family to live in poverty. F.V. Chizhov had to endure many hardships during his studies at the gymnasium and repeatedly seek help from 'benefactors', which likely stayed with him for life. It is not surprising that Fedor Vasilyevich Chizhov bequeathed all his fortune to create a network of special educational institutions in the Kostroma province.
