Plans to renovate the historic building at 51 Bolshaya Morskaya Street in St. Petersburg have been called into question. Restoration work has not begun due to a criminal case and the building's status as a historical monument.

According to a historical and cultural assessment published in September, the project calls for preserving key architectural features. It is planned to leave the location and dimensions of the main building, the height of the roofs, and the structure of the inner courtyard unchanged. Particular attention is paid to preserving the external appearance and decorative elements of the interiors in order to emphasize the historical value of the object. At the end of last year, the Committee for State Control, Use, and Protection of Historical and Cultural Monuments issued a permit to carry out work to preserve the building. However, the mansion is still under arrest as part of a criminal case. This status does not allow work to begin. The reason for the criminal case was an appeal by city preservationists to the Investigative Committee to verify the legality of the partial dismantling of the monument. After the scandal erupted, the public succeeded in getting the previous order on protected items overturned in court. In November 2023, a new list of protected characteristics of the monument was approved.
