The Palace has 298 large rooms with a total area of 34,236 m² (368,510 sq ft), 92 windows in the front part of the building and another 36 inside the building.

Decoratively, the central hall shows a figurative mosaic including various representations of a gothic bestiary, concentrically arranged: two-headed eagles, dragons, griffons, lions.
The hall is superposed by a glass ceiling room, where initially a greenhouse was arranged.

In spite of its archaic-looking design, the Palace was designed so to integrate modern materials and technologies.
Thus, the stone blocks were replaced with light and much cheaper materials.
Besides, some rooms were decorated using a special material licensed by Henri Coandă, under the name of bois-ciment and imitating the oak wood.
Decorative ironmongery elements are also remarkable and they can be admired for instance on the doors of the Voivodes’ Hall.
The building was also equipped with high-tech facilities for those times, such as electric lighting, (pneumatic) heating, ventilation system, thermostat, vacuum cleaners, which were all directed from the machinery room, at the underground level.
Taking also into account the 14 fires that affected the previous buildings, Berindei (the main architect) treated the wooden structure of the attic with an ignifugeous product called orniton, while for the roof he used a special material, named eternite.
