Which housing type is least likely to have complex floor plans?

One-story houses, often referred to as single-story or ranch-style homes, typically feature simpler floor plans compared to other housing types. The design focuses on efficiency and accessibility, which generally results in a straightforward layout. All the rooms are usually situated on the same level, making it easy to navigate from one area to another without the need for staircases or multiple levels.

In contrast, two-story houses, split-level houses, and multi-level houses often include various levels, which can lead to more complex configurations. These designs may incorporate different zones for living, dining, and sleeping areas spread across multiple floors, resulting in a floor plan that can be more intricate to navigate and understand. The presence of stairs and changes in elevation contribute to the complexity seen in those housing types, making one-story houses comparatively less complex in their architectural layout.
