The estate of E.V. Tatischev on Petrovsky Boulevard is a significant historical and architectural ensemble of Moscow in the classical style and is recognized as a cultural heritage site of federal significance. It is one of the first ensembles built along the former passage by the walls of the demolished White City. The main house of the estate is executed in the best traditions of Russian classicism. The layout of the estate was expressive: the street facades of the side wings, symmetrically located relative to the main house, were similar, but their planning structure differed. The courtyard behind the house was surrounded by service buildings, concealing the irregular shape of the plot.

Around 1850, the estate passed from the heirs of Tatischev to the well-known entrepreneur Lev Katuar, who commissioned architect A.S. Kaminsky to reconstruct the ensemble. After Katuar's death in 1899, the estate was owned by his widow, children, and grandchildren. The eastern wing housed the apartment of A.L. Katuar, where the composer and educator G.L. Katuar later passed away.

The eastern wing, an example of an urban estate from the late 18th century, was reconstructed in the mid-19th century, partially preserving its classical decor. Initially, it had a street facade with 4 axes, but it was already extended with an L-shaped addition from the courtyard, dictated by the boundary of the estate. Although Kaminsky's project did not foresee the reconstruction of the eastern wing, it actually occurred: in subsequent plans, it is shown as more elongated, and the courtyard buildings expanded to the east, remaining single-story.

In 1914, the courtyard addition became two stories, a new entrance vestibule appeared, and a single-story volume was attached to the end. The first floor and basement have Monier vaults. Drawings of architect Z.I. Ivanov's project, which provided for plastering and decorating the facade, have been preserved, but this was not realized. The facade remained modest, with a low central pediment.

After the revolution, the wing was used as communal housing, then as a clinic. In 1977, the street part of the wing was transferred to the Institute of Reflexology, while the courtyard part was given to a kindergarten, which still operates there today. The wing is recognized as a cultural heritage site of federal significance.
