The purpose of this discussion is to examine how the revolutionary introduction of economically variable steel impacted Louis Sullivan's overall design project. The discussion will explore steel and the benefits it brings. Additionally, the discussion will examine Louis Sullivan's contribution to high-rise steel construction and what others did during the same period, comparing it to his innovative Wainwright Building, in St. Louis (1890) . The discussion will focus on and analyze an article published by him in 1896 "The Great Office Building Artistically Considered", on how ornamentation and structural mass become one. We can therefore apply this philosophy of ornamentation to the Wainwright Building. Through this exploration, it is hoped to better understand the influence of the introduction of steel on Louis Sullivan's project to create a new American architecture. Before the end of the 19th century, a high-rise building depended on the strength of the walls. to maintain the charge. The taller the construction, the more stress was added to the building. Due to the weight limitations that "load-bearing" walls could perpetuate, any large-scale construction at this time required walls of colossal size, thus leading to limitations on overall height. As the end of the 19th century approached, the development of economical and adaptable steel began. , which changed the rules regarding weight limitations. At that time, America was experiencing great economic and social development, which generated great potential for architecture. As the demand for a more urbanized society grew, larger and larger buildings were required. Large-scale steel manufacturing was the primary driver of the ability to...... middle of paper ......ise architecture at the time is undoubtedly one of its most great achievements. Louis Sullivan brought to light the phrase “form follows function,” but one could argue that this is hypocritical from the man who focused too much on ornamentation. Through extensive research, this discussion manages to conclude that, as Sullivan himself stated, a building without decoration could be a magnificent building. Then again, when it comes to the Wainwright Building, when the ornamentation and construction come together as one, the building is also magnificent. Interested in the inspiration behind Louis Sullivan's infamous ornamentation, this discussion explores Sullivan's correlation between society and architecture in his work. Through the use of ornamentation, Sullivan works to achieve organic architecture aspiring to the relationship between man and nature..
