Before the restoration in the 2000s, buildings No. 17 and 19 on Ostozhenka looked like a single structure. This was also the case in the 1920s when a clinic opened here. However, building No. 17 is a separate income house, built in 1901 by order of the famous tea trader V.I. Gryaznov. The project for the building was developed by the renowned architect Lev Kekushev.

In 1900, the Kekushev family acquired a plot on Ostozhenka Street, where the architect planned to build a mansion for himself and his wife. Kekushev's neighbor was V.I. Gryaznov, who commissioned the architect to construct an income house. In 1901, a project was submitted to the Administration, signed by the young architect S.S. Schutzman. However, specialists believe that the building undoubtedly belongs to Kekushev. Schutzman was a regular assistant to Kekushev but unfortunately lost his sight early. Despite this, Kekushev continued to support him and provide him with orders, which possibly explains why the project was signed in the name of the assistant rather than the master himself.

The Gryaznov House on Ostozhenka is a small three-story building with a semi-basement. The facade is adorned with a light balcony, and the corner, taller part of the building features semicircular windows with knight masks. One of the masks is visible from Ostozhenka on the main facade, while the other is on the side facing the square. The entrance is highlighted by a risalit with a smoothly curved cornice. The semi-basement and third-floor windows have rounded corners, characteristic of Art Nouveau. Lacy wrought-iron railings decorate the balconies, and wrought-iron grilles adorn the windows of the basement floor. The walls of the first floor are finished with rustication, while the second and third floors are clad in flesh-colored ceramic tiles. To the right, the Gryaznov House adjoins the Kekushev House and appears as a single entity.

To the left of the house is now a small square. Until 1935, there stood the Church of the Resurrection of the Word on Ostozhenka, and the design of the house's facade echoed that of the church, but this combination is no longer possible to appreciate.

In the 1920s, buildings No. 17 and 19 were combined, and a Moscow clinic was established there, where surgeon A.I. Bakunin worked. It was here that Patriarch Tikhon died in 1925. In the 1980s, a sign at the entrance to the clinic read "Inpatient Care." In the 2000s, the Gryaznov income house was visually separated from the neighboring building.

In 2019, the restoration of the facades of the income house was completed.
