The aim of the study is to find out to what extent dominant ideologies of post-war decades shaped modern mass housing and to engage a discussion about potential heritage of the phenomenon. Analysis is based on the district of Lazdynai (Vilnius). The paper is committed to demonstrate that transition, considered by Tunbridge & Ashworth as a factor of dissonance in heritage, made messages and meanings embedded in mass housing obsolete, and in some cases even undesirable.
