Early Architectural Innovations

Before skyscrapers, buildings were limited in height by the load-bearing capacity of their walls. As buildings grew taller, their walls had to be proportionally thicker, which was impractical beyond a certain height. The crucial innovation that enabled the rise of skyscrapers was the development of iron and steel as building materials.

The use of iron and later steel in building frames marked a significant shift from traditional construction methods. These materials could support much greater weights and heights than stone or brick, allowing for the construction of taller buildings without the limitations imposed by thicker walls. This structural innovation was complemented by advancements in other areas, such as the development of safety elevators by Elisha Otis, which made high-rise buildings practical.
