High rise living quarters built in late socialist and post-socialist time in a post-soviet city present a unique phenomenon by its extent, morphological dimensions and public perception. According to the results of the international comparative study which included St. Petersburg, although segregation and polarization have not yet spread in this city, socio-spatial differentiation actively develops in high rise living quarters. Morphologically different types of such quarters shape different types of social stratification. Dynamics of "social elevation", perception of environment, and hence market attractiveness of such quarters differ as well.
