The building at 14 Neglinnaya Street is often mistakenly referred to as the Sandun Baths, and this label can even be found on pre-revolutionary postcards. However, this is incorrect. In pre-revolutionary times, both the income house and the baths were owned by V.I. Firsanova. Both buildings were constructed in the mid-1890s according to the designs of architects B.V. Freidenberg and S.M. Kalugin. In the courtyard section of the income house, there was a bath department before the revolution. But the famous "Sanduny" is located behind this building, in the second line of houses.

The house, facing Neglinnaya and situated between Sandunovsky and Zvonnarsky lanes, was originally built as an income property, with residential apartments and commercial spaces. Sometimes it was referred to as the "Sandun Passage."

The facades of the building are richly decorated with stucco: masks in the form of lion heads, the head of Triton, figures of a mermaid with a lyre and a young man on sea horses. On the dome, there are figures of tritons, and on the roof, sculptures of bathing boys. A three-part arch with a beautiful gate grille leads to the inner courtyard, designed in a "Moorish" style with numerous sculptures and a lost fountain composition. All this rich decoration of the facades served as architectural advertising, inviting people into the world of the bath kingdom.

Above the arch under the clock, the Roman numerals "MDCCCXCV" can be seen, indicating the year of construction of the house as 1895.

Before the revolution, the upper floors of the building housed luxurious rental apartments, one of which was occupied by the owner of the house. The side wings facing the alleys also contained residential spaces. In 1902, the five-room apartment on the first floor was rented by A.P. Chekhov with his wife O.L. Knipper-Chekhov. Their guests included A.M. Gorky, K.S. Stanislavsky, V.I. Nemirovich-Danchenko, V.F. Komissarzhevskaya, I.A. Bunin, V.A. Gilyarovsky, and artists from the Art Theatre.

On the first floor facing Neglinnaya Passage, shortly after the house was built, a music store owned by P.I. Yurgenzon was established, which remained here for over a century, until the 2000s. Currently, the building houses various organizations, restaurants, and shops.

The income house of Firsanova is protected by the state as a cultural heritage site of regional significance.
