What is a split level type house?

A split-level house is a style of residential architecture characterized by multiple levels of living space that are staggered, rather than being built on a single level. Typically, it has three or more levels, with the main floor slightly elevated above a lower level, often featuring a basement or a sunken living room. This design allows for a more efficient use of space and can create distinct areas for different activities, such as living, sleeping, and recreation. Split-level homes became popular in the mid-20th century, especially in suburban areas.
