Discover Denver Style Spotlight: Second Empire
Second Empire style is often associated with haunted houses, most famously the house in Alfred Hitchcock’s 1960 film Psycho. Originating in France during Napoleon III’s reign (1852–1870), it gained international popularity through World’s Fairs and early home pattern books. Its popularity peaked before Denver’s major building boom, making it uncommon here.
The style’s defining feature is the mansard roof, a boxy double-sloped roof that creates room for an additional half or full story. Despite a popular myth about avoiding taxes on an extra floor, the roof’s practical advantage was providing more usable space.
Look for: mansard roofs, dormers, roof cresting, projecting bays or towers, moulded or arched window surrounds, pediments, and decorative brackets.
Fun fact: The mansard roof takes its name from 17th-century French architect François Mansart (1598–1666). He didn’t invent it, but he helped popularize it.
