The paper presents issues of style of modern architecture of the XX - early XXI centuries gravitating toward ideas of the big macroscopic spaces. Various artistic manifestations brightly reflecting the new tendencies of the era determinate its development. The architecture of postmodernism that provided various style alternatives began more gravitate towards reflecting the great ideas of the ‘macrocosm’ by the end of the 1980s and 1990s. As against the ancient monumental buildings that act as bearers of traditional functions, modern architecture presented a new philosophy of looking at the world, society and the era as a whole. Modern macroscopic complexes form a new sphere of life- sustaining activity by reflecting daily needs in a comfortable and ecologically significant environment.
