LEGO Architecture Flatiron Building 21023 Building Instructions page 5

With its steel skeleton structure, the construction of the building was
carried out rapidly and without major incident. While other New York
skyscrapers at the time were often thin towers rising from pedestal-like
blocks, the Flatiron was a single massive structure. This radical design,
combined with its great height and unusual shape, created a great deal
of debate as the building neared completion in 1902.
Many New Yorkers believed the structure would be unstable and would
fall over at the first gust of wind. The building had even been nicknamed
"Burnham's Folly" and bets were placed on how far the debris would
reach when it blew over. Strong winds came and went, and the Flatiron
Building withstood them—as it continues to do today, over a century
later. It is proof that the structure was not only a strong architectural
idea, but a groundbreaking engineering marvel as well.
