Several important members of this group worked at one time in Jenney’s office, including Daniel Burnham (who would go on to design New York City’s iconic Flatiron Building), John Root and Louis Sullivan. Jenney’s achievement paved the way for the work of a group of architects and engineers that would become known as the Chicago School together, they would develop the modern skyscraper over the last years of the 19th century and the first years of the 20th. In addition to being the first of a new generation of steel-framed skyscrapers built in cities across America and the world, the building set the standard for various other building innovations, including rapid, safe elevators, wind bracing and modern plumbing. In 1890, two additional floors were added at the top, bringing the total height to 180 feet (55 meters). During its construction, city authorities were so worried that the building would topple over that they halted construction for a period of time so that they could ensure its safety. The Home Insurance Building was completed in 1885 it originally had 10 stories and stretched 138 feet in the air. Buildings with this type of frame could also have more windows, as the steel frame supported the building’s weight and the stone or brick exterior merely acted as a “skin” to protect against weather. As a result, the walls of the building didn’t have to be as thick, and the structure could be much higher without collapsing under its own weight. With this new method of construction, lighter masonry walls could be “hung,” a bit like curtains, from the steel frame. Steel was not only lighter than brick, but it could carry more weight. This was in stark contrast to earlier structures, which were supported by heavy masonry walls. His revolutionary design utilized an inner skeleton of vertical columns and horizontal beams made out of steel. In 1883, William LeBaron Jenney was appointed by the Home Insurance Company in New York to design a tall, fireproof building for their Chicago headquarters. The Home Insurance Building, located at the corner of Adams and LaSalle Streets in the Loop, Chicago’s business district, became a leading example of this era of new construction.ĭid you know? By the time New York got its first steel-frame skyscraper in 1889-the Tacoma Building on Wall Street-Chicago had no fewer than five such buildings, beginning with the Home Insurance Building, completed in 1885. Instead of wood, the new buildings going up in Chicago were made largely of stone, iron and steel, a relatively new material. Following the Great Chicago Fire of 1871, a boom of new construction would revitalize the city’s economy and completely transform its skyline.
