About this deck
A skyscraper is not a tall building. It is a tall building made possible by three specific 19th-century inventions — the steel frame, the safety elevator, and the central HVAC system — that together permitted occupied space to rise hundreds of metres above the ground. Key sections include: Sky scrapers.; Opening Up.; Chapter I What counts.; Chapter II The Chicago school.; Chapter III "Form follows function."; Chapter IV New York learns.; Chapter V The Empire State.; Chapter VI The Chrysler.; Chapter VII The postwar tower.; Chapter VIII The tube structure..
