The ensemble of buildings at Nikoloyamskaya Street, 51, is often referred to as the estate of Skorospelov, as it was under merchant A.A. Skorospelov that the property acquired its current appearance. In the vestibule of the left door of the estate house, a mosaic with the date "1871" is laid on the floor, which likely indicates the completion of the reconstruction. However, the history of the estate began much earlier.

Experts have always noted the unusual location of the house: it stands not parallel to the red line of the street, but deep within the courtyard. This usually indicates the antiquity of the building, its existence before the regulation of Moscow streets and the emergence of modern red building lines in the 1770s.

The main house of the estate consists of structures from different eras. At its core is a stone chamber from the late 17th century. In the mid-18th century, the house was significantly reconstructed by merchant S.P. Vasilyev, who also financed the construction of the famous bell tower of the Spaso-Andronikov Monastery, which was destroyed in the 1930s. From the basement of the house, one can access a corridor with a stone vault.

Some historians believe that house No. 51 is connected by an underground passage to the Alexeyevskaya Church located opposite, although this passage is now blocked. The wings appeared when, in the late 18th century, the estate was inherited by merchant P.Y. Pishchalnikov, who owned the neighboring plot at Nikoloyamskaya Street, 53. The ancient estate services were replaced with stone wings, which were positioned end-to-end with the red line of the street, symmetrically relative to the main house. Despite their different sizes (the western wing extends deeper into the plot than the eastern), these structures brought order to the composition of the estate and organized the ceremonial courtyard.

The two-story western wing was later reconstructed, reflecting the tastes of the new owners and following fashionable trends, while the eastern wing retained its main features.

In 1853, the new owner S.V. Morozov expanded the house with extensions, adorned the ceremonial enfilade with artificial marble, painted the ceilings, installed fireplaces, and covered the floor with patterned parquet. This decoration has largely been preserved.

The western wing was also updated: its facades were decorated with stucco in the Baroque style.

The western wing, like the main house with the eastern wing, is a cultural heritage site of federal significance.
