The term for the total floor area within exterior walls, including corridors and other spaces, is:

When measuring space inside a building, the total floor area within the exterior walls includes every enclosed area—corridors, lobbies, stairs, restrooms, mechanical rooms, and other spaces alike. This comprehensive measure is known as gross floor area.

Since the description specifies the entire footprint inside the walls, including corridors and other spaces, the term that fits is gross floor area.
