Here are some examples:
* A ranch house: These are often one story high, with all living spaces on the ground floor.
* A small apartment building: While some apartment buildings are multi-story, some are only one story tall.
* A single-story commercial building: Businesses like shops, offices, or restaurants can be built in one story.
The phrase "one story high" is used to indicate that a building is relatively low in height compared to buildings with multiple stories.
