The internal built volumes of over one million square metres (more than ten million square feet) assume a staggered formation within the triangulated steel mega frame, extending flush against the sloping facetted glazed outer skin. This terracing creates a series of wintergardens, which form a breathable second layer and thermal buffer for the main building, shielding the interior spaces from Moscow’s extreme summer and winter climates. A vertical louvre system sheaths the internal facades to ensure privacy for the individual apartments.
