The 138-metre building consists of a central 24-storey building and two side buildings with a variable number of storeys ranging from 11 to 15. The exterior walls of the skyscraper are clad in natural
limestone, while the ground floors are clad in red granite. The interiors of the building are more modest than in other
Stalinist skyscrapers. For example, stainless steel was used in the front lobby and there are no expensive materials or picturesque panels. The central building on the courtyard side had an assembly hall (on the ground floor) and an exhibition hall (on the basement). A tunnel was created along the perimeter of the basement with an entrance from the side of Komsomolskaya Square. It was intended for trucks serving the services of the building. The building was originally built for the needs of the Ministry of Railways. However, by 1951, when the works were completed, a new union agency
Mintransstroi existed and it got the offices in the central block of the skyscraper. All flats had refrigerators, built-in-furniture and sinks with a crusher to destroy large waste in the kitchens. The kitchens also had access to a rubbish chute. In addition to the traditional ventilation system, the house had central air conditioning. For this purpose, outdoor air was filtered and passed through a humidification system before reaching a temperature of +15 °C. Then, depending on the season, the air was heated to the right temperature. All high-rise buildings were equipped with a centralised dust extraction system, which consisted of a system of brushes and hoses located in each flat, a system of pipes running along with the building and dust extraction stations installed in the basement. The collected dust was filtered and discharged into the sewage system, and the purified air from the system was discharged into the street.
Boilers were installed in the basement to provide heating for the skyscraper. == History ==
