What defines a Modern Multi-Story House?

A Modern Multi-Story House is characterized by having multiple levels with distinct stories. This design allows for various functional spaces to be distributed over several floors, which is a hallmark of modern residential architecture. Multi-story homes often take advantage of vertical space, offering benefits such as improved views and separation of living areas.

The other options do not align with the definition of a modern multi-story house. A single level of living space clearly does not fit the multi-story concept. Architectural styles of the 18th century and a focus on historical design elements skew towards traditional designs rather than contemporary, modern interpretations. Thus, the defining feature of a Modern Multi-Story House is its construction over multiple levels, facilitating a variety of layouts and living arrangements.
