A TYPE 1 building that has stairwells at either end of the building is categorized as which layout?

• A. Combination
• B. Center hallway
• C. Center core
• D. Atrium

Answer: (B)

Identifying floor plan types by where the stairs are located relative to a long corridor. When a Type I building uses a single long central corridor with stairwells at opposite ends, that arrangement is called a center hallway layout. The corridor runs through the building with rooms or spaces on both sides, and the ends of the corridor house the stairs to provide clear egress routes. This differs from a center core layout, where the main vertical circulation sits in a central block rather than at the ends; an atrium layout features a large open vertical space rather than a straightforward corridor; and a combination would mix features from multiple layouts. So the description fits center hallway.
