Khrushchyovka () is a type of low-cost, concrete-paneled or brick three- to five-storied apartment building which was developed in the USSR during the early 1960s, during the time its namesake Nikita Khrushchev directed the Soviet government. ==History== Traditional masonry is labor-intensive; individual projects were slow and not scalable to the needs of overcrowded cities. To ameliorate a severe housing shortage, during 1947–1951 Soviet architects evaluated various technologies attempting to reduce costs and completion time. During January 1950 an architects' convention, supervised by Khrushchev (then the party director of Moscow), declared low-cost, quick technologies the objective of Soviet architects. Two concrete plants were later established in Moscow (Presnensky, 1953; Khoroshevsky, 1954). By this time, competing experimental designs were tested by real-life construction, and prefabricated concrete panels were considered superior. Other possibilities, like in situ concrete, or encouraging individual low-rise construction, were discarded. During 1954–1961, engineer Vitaly Lagutenko, chief planner of Moscow since 1956, designed and tested the mass-scale, industrialized construction process, relying on concrete panel plants and a quick assembly schedule. During 1961, Lagutenko's institute released the K-7 design of a prefabricated 5-story building that became typical of the Khrushchyovka. 64,000 units (3,000,000 m2 (32,000,000 sq ft)) of this type were built in Moscow from 1961 to 1968. In Moscow, space limitations forced a switch to 9 or 12-story buildings; the last 5-story Khrushyovka was completed there during 1971. The rest of the USSR continued building Khrushyovkas until the end of communism; millions of such units are now past their design lifetime. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Khrushchyovka」の詳細全文を読む スポンサード リンク
