Attempts are being made to restore many of the city's best-kept examples of pre-Soviet architecture. These restored structures are easily spotted by their bright new colors and spotless façades. There are a few examples of notable, early Soviet avant-garde work too, such as the house of the architect Konstantin Melnikov in the Arbat area. Many of these restorations were criticized for alleged disrespect of historical authenticity. Facadism is also widely practiced. Later examples of interesting Soviet architecture are usually marked by their impressive size and the semi-Modernist styles employed, such as with the Novy Arbat project, familiarly known as "false teeth of Moscow" and notorious for the wide-scale disruption of a historic area in central Moscow involved in the project.
