[2] Langman coordinated the height parameters of the building with the Mossovet hotl — nearly the same height of both buildings was supposed to conceal the large relief difference from Lubyanskaya to Manezhnaya squares and create the illusion of straightness of the front street, running to the new architectural dominant of Moscow - the Palace of the Soviets.

[2] Nikita Khrushchev, then head of the city, recalled how the architects discussed the project with the future "owner" of the building Vyacheslav Molotov (chairman of the Labor and Defense Council).

Stylistically, the design of the State Duma building combines both elements of constructivism, as well as monumentality and representativeness — features inherent to the next period of the Soviet architecture.

[3] By the beginning of the exterior decoration, the deposits of marble-like limestone near Kolomna, turned out to be exhausted, and slabs removed from the Cathedral of Christ the Savior, demolished in 1931, were used instead.

The granular plaster covering the internal facade is made of stone chips, which were obtained by grinding marble facings of Moscow churches massively demolished in the 1930s.

The same materials were used to decorate the Okhotny Ryad metro station being built at that time, one of the exits of which was originally planned to be placed inside the Building.
