Mansard-style, also referred to as mansard architecture, describes a design approach centered on the use of the mansard roof—a double-pitched roof with a steep lower slope and a flatter upper slope on each side. This configuration creates additional habitable attic space, often illuminated by dormer windows that break the roof surface. The term can apply to both the roof itself and the broader architectural idiom that accompanies it, including façade treatment and interior spatial planning that emphasizes vertical rhythm and elaborate detailing.

The style is named after the 17th-century French architect François Mansart, who popularized the roof form in France. Although variations of double-pitched roofs existed earlier, Mansart’s promotion helped embed the design in architectural practice. By the 18th and 19th centuries, the mansard roof became a hallmark of an urban, sensibly dense aesthetic that could add usable space without enlarging the building’s base.

In the 19th century, mansard-style architecture reached a peak of popularity in France during the Second Empire and spread to many European cities, including Paris, Vienna, and parts of Central Europe. In these contexts, the style is often associated with grand townhouses and public buildings, where the roofline contributes to a dramatic skyline and a sense of architectural opulence.

Today, mansard-style is frequently encountered in historic preservation, restoration projects, and new constructions that seek to evoke late 19th-century Parisian or Central European urban character. It remains notable for balancing functional attic space with a distinctive, expressive roof silhouette.
