The address Ostozhenka, house 21, is known as a place associated with architect Lev Kekushev. However, in 1901, the neighboring house 19 also belonged to him. These buildings were considered a single property and income house of the architect. The house was built two years after Kekushev's mansion and was registered in the name of his wife Anna Ionovna.

Lev Kekushev married Anna Bolotova, the daughter of a nobleman from Kremenchug, in 1897, when he was already a recognized master. The family moved to Ostozhenka, where Kekushev built a mansion and two income houses: house 17, owned by tea merchant V.I. Gryaznov, and house 19. Gryaznov rented the first floor for his tea shop, while the upper floors were rented out.

The architectural design of Kekushev's income house cannot be called lavish, but it attracts with its simplicity and modest decor. The smooth lines of the cornice, a small balcony above the entrance to the shop, and calm window frames make the building interesting. The decor features chestnut leaves that frame the owners' monogram on the semicircular attic and fill the cartouches between the windows of the second and third floors.

There are disputes surrounding the owners' monogram, which contains the letters 'A' and 'S'. It is possible that the letter 'A' appeared during the Kekushev's time and referred to Anna. After them, the house was owned by Sergey Astakhov, and the second letter of the monogram may relate to him.

During the Soviet era, the house was used as a residential building, the arch created by Kekushev was bricked up, and an entrance was made there. During the restoration in the 2000s, the arch was restored, and patterned gates in the Art Nouveau style were installed.
