Six-hundred square meters and a structure better described as a hut than as a house. The majority of Dachas were humble at best, but they were mansions to the Soviet citizens lucky enough to have one. Life in the Dacha world was the life most mid-20th century Soviet citizens dreamed of. The ability to be away from the world, to have a small vegetable patch, and to have a place that was, more or less, your own was the dream for many Russians.
Under Stalin these prime pieces of real estate were only for party elites, but once the Khrushchev era dawned the privilege of inhabiting a Dacha was opened up to regular people. The trade unions were each allocated a certain number of dachas and they distributed them to their members in varying ways.
The chance to escape the dirty city air was an exciting prospect in and of itself, so the couple hours long ride on electric trains out to Dacha country were definitely worth it to Russians. They saved all their weekly effort to care for the Dachas that were not technically theirs. The care and time spent on Dachas was only less than the care for their children. Even though the state technically owned all Dachas the people who were lucky enough to have their own Dacha treated them like their most prized possession.
The Dacha mystique was so strong that even when someone was under suspicion there was hesitation from the trade unions to revoke the Dacha. Perhaps if the Soviet Union had given their people more things to feel personal responsibility for they may have been more successful as a country.
