In 1955 all “unnecessary architectural details” were cancelled. Rapid urbanization of the 1960s-1980s changed the Soviet urban planning policy. The natural city centers were no longer expanded. Instead, new so-called “micro-districts” or “sleeping districts” were constructed away from the downtowns all over the Soviet Union. These areas were meant to be self-sufficient with shops, schools and kindergartens in their centers and parks on their flanks.
Architecturally these Soviet “dream cities” look very similar to each other. Multi-storey apartment blocks surround large open spaces currently overfilled with cars. There are few interesting buildings as hundreds of white apartment blocks used to be built on the same design, devoid of any unique details. The Union-wide requirements for the apartment layouts were tight: not more than 9 m2 of living space per person, kitchen not larger than 6 m2, bathroom together with toilet not larger than 3,5 m2 (later this was altered to permit installing bath and WC in separate small rooms). Nevertheless, for a person outside the former Iron Curtain it may be interesting to explore at least a single such zone.
There are Soviet functionalist residential blocks in the city centers too. Similary lacking architectural details these buidings were usually reserved for the upper flanks of Soviet social hierarchy and therefore the limitations on apartment sizes and prestigious interiors were „relaxed“.
Public buildings in the city centers are in some cases more interesting, such as the brutalist Palace of Sports and Concerts in Vilnius (Žirmūnai) (1971) or the pompous interior of National Opera and Ballet Theater in Vilnius (Naujamiestis). But for every unique buiding there are many other pubic buildings built on blunt „universal“ designs created elsewhere in the Union.
Visaginas town that was entirely built in the 1970s and 1980s for workers of nearby nuclear power plant is a good example of the late Soviet period city.
Elektrėnai is another Soviet town built for power plant workers, but this power plant is conventional and its workers were not regarded in the same high esteem as the nuclear specialists, therefore Elektrėnai lacks much of the work put into the urbanistic plan of Visaginas.
Every main city is surrounded by Soviet districts (e.g. Lazdynai, Karoliniškės and Fabijoniškės in Vilnius, Šilainiai and Kalniečiai in Kaunas, Bandužiai in Klaipėda). There are Soviet public buildings every city center, contrasting with their centuries-old environs. The towns and villages have smaller two-floored aparment blocks and private prefab detached homes dating to this era. In fact the late Soviet period is the one easiest to spot in Lithuanian architecture.
Due to the low building quality of the era and the sheer number of people living in such homes, problems like bad insulation and subsequently high heating prices in the microdistricts are considered important on the level of national politics. A campaign of Soviet apartment block renovation was initiated but it haven't yet fully took off. You may recognise renovated homes as they are newly repainted.
Another heritage of the late Soviet period are the so-called „collective gardens“: a certain plots of suburban land urban dwellers were allowed to farm. This popular pasttime (and a source for additional income in a society where personal revenues were under a tight state control) has been slowly moving into obscurity after independence, with many „collective gardens“ on prime land now transformed into districts of prestigious private detached homes.
