What is a "stairwell"?

A stairwell is an enclosed vertical space within a building that houses a staircase, providing access to different levels. It typically includes walls, a ceiling, and sometimes windows, allowing light to enter the area. Stairwells serve both functional and aesthetic purposes, facilitating movement between floors while also contributing to the building's overall design. They can be found in residential, commercial, and public buildings, and may vary in size and style. In addition to connecting levels, stairwells often play a role in emergency exits, ensuring safe evacuation in case of emergencies.
