One of the first known owners of the plot was Colonel Fyodor Khomutov and retired lieutenant Alexey Khomutov. In 1782, they sold it to Captain-Lieutenant of the Life Guards Vasily Obreskov and his wife Anna. The estate had a traditional layout: the main wooden house was located along the red line of the alley, and on both sides of it, along the borders with neighboring plots, there were residential wings, the southern wooden and the northern stone. After the fire, the layout of the estate remained the same, but a garden was planted in place of the burned southern wing.

The northern wing has survived to this day, unchanged in its configuration and size from the late 18th to early 19th century. Researchers have been unable to find the original drawings of its facades and plan. After the fire of 1812, the wing received an Empire-style finish. The two-story stone building with a basement faces the end facade towards the line of Staro-Konyushenny Alley and extends deep into the plot. The main facades are the street and the southern side, which was previously oriented towards the main house of the estate. The central part of the southern facade is highlighted by a three-window arrangement, a triangular pediment, and a second-floor balcony with an elegant metal railing.

The facades are decorated with ribbon rustication on the first floor, while the second floor features a window sill and a niche. The horizontal windows of the first floor, located quite high, draw attention, indicating the presence of a stable below in the past.

In the 1980s, the building underwent major renovations and was adapted for the needs of the Cambodian embassy: foundations were strengthened, ceilings were replaced, and the spatial planning structure of the wing was altered. Only the transverse load-bearing walls of the original layout remain; the vaults and ceilings have been lost. At that time, interior finishing was carried out, which has been preserved to this day, including the grand wooden staircase, columns, panels, and other elements.

Today, this is the only surviving structure of the urban estate, which still houses the Cambodian embassy. The historic building has protective status and is recognized as a cultural heritage site of regional significance.
