"Haussmannian" refers to the architectural and urban planning style associated with Georges-Eugène Haussmann, who redesigned Paris in the mid-19th century. This transformation included wide boulevards, uniform building heights, and the incorporation of parks and public spaces, aimed at improving traffic flow and public health. The Haussmannian style is characterized by its elegant facades, typically featuring stone or brick, large windows, and wrought-iron balconies. This design not only enhanced the aesthetic appeal of the city but also facilitated better light and ventilation in urban areas, setting a precedent for modern city planning.
