Main Administration for Service to the Diplomatic Corps (GlavUpDK) under the MFA of Russia is repairing façades of the 1902 Gutheil mansion (8 Prechistensky lane, bldg. 1) a federal cultural heritage site.
It was built in 1903 following a project by William Walcott, a British architect who also designed the façades of the Metropol Hotel in Moscow. Expressive decorative mouldings in Rocaille patterns are the focus of the façades’ architecture. 
When planning the development of Prechistensky lane 6, 8 and 10, Moscow Trade and Construction Company’s shareholder J. Rekk was ambitious: he wanted to build “Stylish houses that, while offering all the engineering conveniences of the Western European urban architecture, would also not suppress Moscow’s local color.” Houses built there stand out on Prechistenka, all different from each other in design and style. J. Rekk that would customize them for their future buyers’ personal tastes. After the construction was complete, linden trees were planted in front of number 8’s main façade. Some of them are still there now.
The first owner of the building was Karl Gutheil, owner of one of the largest Russian sheet music publishing houses, A. Gutheil. In 1913, it was sold to Dionisy Karzinkin, an offspring of famous Moscow merchant family, Director Candidate of the Great Yaroslavl Manufacture Trade and Indistry Company.
After the Revolution, the building housed an orphanage, the Central House of the Child Communist Movement and the Komsomol Central Committee’s Central House of Youth Leaders. In 1958, it was handed over to the Moroccan Embassy. 
The repairs being done by GlavUpDK cover the façades, the glass canopy over the main entrance, doors, windows, grand and service staircases. The effort is going to help preserve the beauty and originality of the building style for future generations of architecture connoisseurs.
For example, they are repairing glazed Metro tiles, restoring parts that have been destroyed. Wall plaster and the foundation ornaments are also being restored. 
Decorative mouldings like panels, cartouches, ornamental profiles are also being restored, along with drawn decor elements that will be repaired and strengthened.
