In 1829, part of the estate was purchased by Senator P. V. Myatlev and was named "Novoznamenka" in memory of the Znamenskaya estate he sold near Peterhof.

At Myatlev's request, a "Gothic" house was built in Novoznamenka, which housed a library with 18,000 volumes of French editions.

The second stone house, which has survived better than the main one, was built later and is of lesser interest. However, the main hall, used for meetings, attracts attention due to its ornate plaster cornice, two original corner tiled stoves, and antique parquet flooring transferred from the main house's hall. The hall is in good condition, ensured by its purpose. The main task of preserving the antiquity is to take necessary measures to protect the described rooms of the main house.

By 1893, the "Gothic house" had seven rooms on the first floor and eight on the second. Excluding the hall on the second floor, the rooms had no artistic decoration. No other information about the original appearance of the building has been found so far.

After the revolution, the hospital was closed, and the estate housed a correctional labor colony. During the Great Patriotic War, the estate's buildings were damaged. In 1957-1960, the building was restored (except for the interior decoration) according to the project of architect M. M. Plotnikov. The exterior appearance was returned to its pre-war state, but the interior space was completely changed: new ceilings and internal walls were constructed. The historical layout was completely lost.

In the 2000s, the building housed a private restaurant called "Gothic House" for some time.
