A mansard roof has two slopes on each of its four sides. The lower slopes are steep while the upper part is nearly flat. Dormer windows often punctuate the lower slopes.
Attic dormers are used in various architectural styles and provide additional living or storage space within a building’s upper levels.
Mansard roofs, commonly used in 19th-century Europe and the US, still feature historic buildings today and remain popular in modern architecture for preserving or creating unique designs.
