Capital City is comprised of two residential towers, individually named after two major Russian cities, Moscow Tower (the taller of the pair) and St. Petersburg Tower. A 17-story business center is housed in the complex. The towers’ form creates the visual effect of a series of stacked boxes offset from one another. This effect is achieved through a slight cantilever on only two façades of each vertical segment, and thus does not compromise the continuity of the towers’ main vertical structure. A mechanical floor demarcates each 15-floor segment and integrates the structural system. The Moscow Tower contains five such segments while the St. Petersburg Tower contains four.
