Why Did Skyscrapers Become Glass Boxes? Economics, Not Modernism

This article explores the shift in US skyscraper design from ornate brick and stone structures to the ubiquitous glass box. Contrary to the popular narrative of a modernist architectural conspiracy, the author argues that the driving force was economic efficiency. Glass curtain walls proved cheaper to construct, faster to erect, and offered greater rentable square footage. While tenants prioritize interior space, developers found that exterior ornamentation had little impact on rental prices, making cost-cutting a primary concern. Though some architects and developers still champion more expressive designs, the relentless pressure for profit maximization has solidified the glass box as the dominant aesthetic.
