more communal apartments. At the same time with the 1930s for senior people began to build houses with separate bedroom apartments, where one family was given the whole apartment. An example of such a house called House on the Embankment (Dom na naberezhnoi) in Moscow, built in 1927–1931, respectively. An important priority during the post-revolutionary period was the mass reconstruction of cities. In 1918 Alexey Shchusev (1873–1949) and Ivan Zholtovsky founded the Mossovet Architectural Workshop, where the complex planning of Moscow's reconstruction as a new Soviet capital took place. The workshop employed young architects who later emerged as avant-garde leaders. At the same time architectural education, concentrated in the Vkhutemas, was divided between revivalists and modernists. In 1919, Petrograd saw a similar planning and educational setup, headed by experienced revivalist Ivan Fomin (1872–1936). Other cities followed suit and the results of the work carried out there were to make dramatic changes in traditional Russian city layout. The first large-scale development templates (generalny plan) were drawn there. The city was planned as a series of new wide avenues, massive public structures and the improvement of workers' housing with heat and plumbing. The first apartment building of this period was completed in 1923, followed by a surge of public-housing construction in 1925–1929. In Petrograd from 1917 to 1919 the first example of the new style was built on the Field of Mars – a monument, "Strugglers of the Revolution", designed by Lev Rudnev (1886–1956). This complex consisted of a series of simple, expressive granite monoliths and became the focal point for further development in Soviet sculptural and memorial architecture. The most famous construction of this time, however, was Lenin's Mausoleum by Alexey Shchusev. Originally it was a temporary wooden structure, topped by a pyramid, with two wings (for entry and exit). In 1930 it was replaced with the present building, built of stone. The combination of dark red and black labradorite enhanced its slender, precise construction. The rapid development of technological processes and materials also influenced constructivist elements in structure design. During the erection of the Volkhov Hydroelectric Station (1918–26, architects O.Munts and V.Pokrovsky), the traditional outline on the window arches is still used (despite concrete being used in construction). The Dnieper Hydroelectric Station (1927–32), built by a collective of architects headed by Viktor Vesnin (1882–1950), has an innovative design featuring a curved dam with a rhythmic pattern of foundations.
