The height of the building was 42 meters, 10 floors. In 1891 two more floors were completed and its height was 55 meters.
The author of the project, American architect William Le Baron Jenny , designed the building in 1884 and proposed an innovative construction technology in which the supporting frame [K 1] was used for the first time (it was made up of cast-iron supports and forged beams [1] ). Traditionally, the role of the supporting structure was performed by external walls. Based on the fact that the strength of steel is about 10 times higher than that of the highest-quality concrete and masonry or brick masonry, the buildings began to rest on a metal frame that supports both external and internal walls. Thanks to the supporting frame, the total weight of the structures was reduced by almost a third. The architect did not dare to completely abandon other supporting structures, therefore the building also had a load-bearing rear wall and granite columns.
