Architecture and style
In the 1930s, a new architectural style was formed in the Soviet Union, later called the Stalinist Empire style or simply Stalinist style. The distinctive traits of the buildings included their substantial size and decorative elements which extend to residential structures. The ornamentation blended classical orders with contemporary symbols like sickles, five-pointed stars, and stylized depictions of Soviet workers. Reflecting the opulence and style of the architectural design, the hotel stood as a monument of the Stalin era, attributed to the architect Oltarzhevsky.
With the inclusion of a 73-meter (240 ft) spire, the total height of the building reaches 206 meters (676 ft). The hotel is designed in a U-shaped configuration. The central section houses the hotel itself, while the side wings, varying in height from 9 to 11 floors, accommodate 255 apartments featuring 2–4 rooms each. Additionally, two five-room apartments are situated within the building. The central tower comprises 34 floors.
The hotel has intricate decoration throughout. Initially, the rooms varied in size and luxury, ranging from single 12 m2 rooms to three-room suites, each complete with a living room and two ensuite bedrooms. A notable feature of the hotel was the winter garden with a fountain located on the second floor. Within the hotel premises, amenities included a post office, telegraph services, a savings bank, as well as several shops offering books, flowers, and theater-related items. Following the hotel's inauguration, an exclusive cafe operated on the upper levels, surrounded by an open terrace providing panoramic views of the city. The hotel staff consisted of 800 employees.
The building featured advanced engineering systems for the time, including centralized air conditioning in addition to the ventilation system. A centralized dust removal system was implemented throughout the entire building, with brushes and hoses in each room and apartment. Dust collected in these systems was directed through pipes to a vacuum cleaner station in the basement, where it was filtered and discharged into the sewage system, while the purified air was released back outside. Hand-held vacuum cleaners were also provided in the hotel. For heating, boilers were installed in the basement of the building. Furthermore, a telephone station with 10,000 numbers was housed within the hotel premises.
