Second Empire homes are some of the most visually distinctive century homes in the United States, known for their steep mansard roofs, ornate detailing, and grand presence. Popular between the 1850s and 1880s, this style originated in France during the reign of Napoleon III and quickly gained popularity in America, particularly for government buildings and private residences.
The defining mansard roof not only gave these homes a striking appearance but also provided practical benefits, allowing for additional living space while maintaining architectural elegance.
The Defining Features of Second Empire Homes

The Iconic Mansard Roof
The most recognizable feature of Second Empire homes is the mansard roof, a two-part design with a steep lower slope and a shallower upper slope. This unique roofing style maximized interior space without increasing the building’s height, making it a practical solution for urban areas where zoning restrictions limited building heights. Often adorned with decorative dormer windows, ornate trim, and cast-iron cresting, the mansard roof gave Second Empire homes a distinct, European-inspired silhouette.
Symmetrical and Grand Facades
Second Empire homes typically feature symmetrical facades with evenly spaced windows and a central entrance. Their exteriors often include decorative moldings, pilasters, and quoins that enhance their formal, elegant look. The use of brick or stone was common, though some homes featured wood siding with elaborate detailing to mimic more expensive materials. The style was frequently used for large estates, townhouses, and government buildings, reflecting its association with prestige and high society.
Ornate Window and Door Treatments
Windows in Second Empire homes are often tall and narrow, with elaborate decorative surrounds. Dormer windows set into the mansard roof add to the home’s grandeur, often featuring curved or triangular pediments. Entryways are typically grand, with double doors, transom windows, and decorative brackets enhancing the home’s stately presence.
Towers and Pavilions
Many Second Empire homes include towers or projecting pavilions, which further emphasize verticality and grandeur. Towers often rise above the rest of the structure, providing a dramatic focal point and allowing for scenic views in more rural settings. These features reinforced the home’s resemblance to European palaces and government buildings, making them a popular choice for wealthy homeowners.
Decorative Ironwork and Balustrades
Ornamental iron cresting was commonly placed along the roofline, adding an extra layer of decoration to the already detailed exteriors. Many homes also featured wrought-iron railings on balconies and staircases, as well as intricate woodwork on porches and verandas. These embellishments reflected the Victorian-era fascination with intricate craftsmanship and decorative excess.
Why the Mansard Roof Was So Popular

Maximizing Interior Space
One of the main reasons the mansard roof became so widely used was its ability to create additional living space without requiring a full additional story. The steep lower slope allowed for spacious attic rooms, which were often used as servant quarters, guest rooms, or extra storage. This practical benefit made Second Empire homes both functional and stylish.
European Prestige and Influence
Inspired by the grand buildings of Paris during the Second French Empire, Second Empire homes became associated with wealth and refinement. The style was particularly popular among American elites looking to showcase their status. The mansard roof became a visual symbol of sophistication, leading to its widespread adoption in both residential and institutional architecture.
Adaptability to Urban and Rural Settings
While many Second Empire homes were built in city settings as row houses or townhomes, the style was equally popular for rural estates and country homes. The mansard roof provided a distinct look that set these homes apart from simpler designs, making them a favorite for those who wanted a home that combined luxury with practicality.
Final Thoughts

Second Empire homes stand out due to their iconic mansard roofs, grand facades, and intricate detailing. The blend of European influence, architectural innovation, and functional design made them one of the most prestigious and recognizable home styles of the late 19th century. While the style eventually fell out of favor, many Second Empire homes have been preserved as historic landmarks, continuing to capture attention with their distinctive elegance.
