I most definitely think Chicago being a “second city” freed Chicago to be more free in exploring alternative ideas in their buildings. I think this because during the time of Chicago’s rebuilding period, they were able to rebuild and construct more monumental buildings than before. Chicago constructed the world’s first skyscraper in 1885, using steel-skeleton construction, which is definitely an alternative idea in building. Th skyscraper had a skeleton frame which includes vertical steel columns in a rectangular grid. The second city’s previous wooden structures that burned down allowed for the production of more steel and stone construction. The city freed Chicago and the economy of Chicago flourished, attracting immigrants from Europe. This freedom led the city to invest in large parks that were extremely well landscaped. Main ideas encapsulated within the buildings were the use of steel and stone since the steel railroad remained and survived the 1871 fire.
