Pyatnitskaya Street is famous for its unusual mansions. One of these houses, number 33, stands out with its sky-blue color and scaly dome. Built in 1866, it was reconstructed in 1894 by Lev Kekushev for Trifon Ivanovich Korobkov. Later, in 1899, architect S.S. Schutzman expanded the building while preserving the original facade decoration. Schutzman and Kekushev often worked together, creating projects such as the reconstruction of the Kuznetsov trading house and the Saarbekov mansion. The second-floor bay window with its expressive decor, forming a canopy over the entrance, particularly attracts attention.

Trifon Korobkov was a well-known Moscow entrepreneur and owner of a paper production company. After his death, the mansion passed to his wife Olga Petrovna. The family also included son Sergey and daughter Olga. Artist Alexander Gerasimov, acquainted with the family through Vladimir Gilyarovsky, painted a portrait of Olga Petrovna, which the family highly valued. Gerasimov also created two paintings at the Korobkovs' country estate. All three works are now housed in the Gerasimov House Museum.

The Korobkov children were also interested in art: the son pursued painting, while daughter Olga was passionate about theater and later became an actress at the Vakhtangov Theater. Sergey Korobkov was a member of the artistic association 'Free Creativity.' From 1935 to 1936, the mansion on Pyatnitskaya housed A.P. Karpinsky, president of the USSR Academy of Sciences, and from 1936 to 1945, academician V.L. Komarov.

In 2013, restoration of the mansion began. Research revealed changes in the layout and finishing of the building, as well as the historical color schemes of the facades and interiors. During the work, the building was returned to its lilac color, the bay window was restored, and the facade decor was renewed. The interiors saw the restoration of stucco and the marble staircase, and the gilding was recreated. The restoration project was recognized as the best in the 'Moscow Restoration, 2015' competition.
