How did the row house new type of housing conserve space?

Row houses, characterized by their shared walls and uniform design, effectively conserve space by maximizing land use in urban areas. By building multiple homes in a row, they minimize the amount of exterior wall surface needed, reducing both construction costs and material usage. This compact arrangement allows for higher population density while preserving open space for other community needs, such as parks and infrastructure. Additionally, row houses often occupy narrower lots, making them ideal for crowded city environments.
