There were fewer examples in Slovakia. An example in Albania is the former New Albania Film Studio in Tirana. In Hungary a Stalinist style was adopted for the new town of Sztálinváros and many other housing, government and infrastructural projects during the 1950s. As in the USSR, Modernism returned in much of Eastern Europe after the mid-1950s, although there were exceptions to this in the most hardline regimes: the enormous Palace of the Parliament in Bucharest is a very late example of neoclassicism, begun as late as 1984 and completed in 1997, soon after the end of Nicolae Ceauşescu's regime in 1989. Latvia features the Latvian Academy of Sciences building in Riga, also known as "Stalin's Birthday Cake". Other areas In East Asia, some examples may be found in North Korea and China like the Beijing Exhibition Center, the Shanghai Exhibition Centre, originally built as the Palace of Sino-Soviet Friendship, and the Moscow Restaurant in Beijing. Examples may also be found in Ulanbaatar, Mongolia. Stalinist styles were used for the design of Soviet embassies outside of the Eastern Bloc, notably the embassy (1952) in Helsinki, Finland. The building, designed by architect E.S.Grebenshthikov, has a certain resemblance to Buckingham Palace in London; this is said to be due to the then Soviet foreign minister Vyacheslav Molotov's liking for the official residence of the British monarch. Stalinist buildings, flanking major city squares, can be found from the eastern parts of Germany to Siberia: Attempts to decrease costs (1948–1955) A change from Stalinist architecture to standard prefabricated concrete is usually associated with Khrushchev's reign and particularly the November 1955 decree On liquidation of excesses ... (November 1955). Indeed, Khrushchev was involved in a cost-reduction campaign, but it began in 1948, while Stalin was alive. A conversion to mass construction is evident in economy Stalinist buildings like Zholtovsky's Bolshaya Kaluzhskaya, 7. Based on masonry, they provided only a marginal gain; there had to be new technology. During 1948–1955, various architectural offices conducted an enormous feasibility study, devising and testing new technologies. Frame-and-panel experiment (1948–1952) In 1947, engineer Vitaly Lagutenko was appointed to direct the experimental Industrial Construction Bureau, with an objective to study and design the low-cost technology suitable for fast mass construction. Lagutenko emphasized large prefabricated concrete panes. He joined architects Mikhail Posokhin (senior) and Ashot Mndoyants, and in 1948 this team built their first concrete frame-and-panel building near present-day Polezhaevskaya metro station.
