What is a stairwell?

A stairwell is a vertical section of a building in which a series of steps or stairs is used to go from one floor to another. Stairwells can be designed in various shapes, sizes, and materials depending on the building's architecture and purpose.

Stairwells are an essential component of a building's design as they provide a safe means of vertical circulation for occupants. In case of emergencies such as fires or power outages where elevators are not usable, stairwells serve as a primary escape route.

Stairwells are typically constructed with sturdy materials like concrete, steel, or wood to provide a stable structure for users. They are required to meet building codes and safety regulations to ensure they are safe and accessible to all occupants, including those with disabilities.

Stairwells may also have handrails for support and visual guidance for users, as well as signage indicating the floor levels and exit routes. Proper lighting and ventilation are also important features in stairwells to enhance user safety and comfort.

Overall, stairwells are a fundamental architectural element in buildings that serve the essential function of providing vertical circulation and emergency egress for occupants.
