Chicago School Architecture — A Guide
Overview
The Chicago School gave the world the modern skyscraper. After the Great Fire of 1871 leveled much of the city, Chicago became a laboratory for architectural innovation. Engineers and architects developed steel-frame construction, enabling buildings to rise far beyond the limits of load-bearing masonry. The result was a new building type that would reshape the skylines of cities worldwide.
Architects like William Le Baron Jenney, Daniel Burnham, John Root, and Louis Sullivan pioneered steel-frame construction and the 'Chicago window' — a large fixed pane flanked by narrower operable sashes. Sullivan's dictum 'form follows function' became the rallying cry of modern architecture. The Home Insurance Building (1885), often called the first skyscraper, used a metal frame to support its walls, fundamentally changing how buildings were conceived and constructed.
Key Characteristics
- Steel-frame construction enabling unprecedented height
- Large plate glass windows (the 'Chicago window')
- Restrained but elegant ornamental programs
- Tripartite facade composition: base, shaft, and capital
- Flat roofs and clean rectangular profiles
- Sullivan's organic ornamental terracotta work

Why Chicago School Matters Today
The Chicago School invented the tall office building and, with it, the modern city. Its innovations in structural engineering, its aesthetic principles, and its belief that commercial architecture could aspire to art laid the foundation for everything from the International Style to today's supertall towers.
