Abstract: A stairway column with an integral ventilation duct. The present system includes a housing having sidewalls forming an interior volume with an open upper end. An opening is positioned along one of the sidewalls, where a plurality of stairs begin, leading from a bottom of the housing to the open upper end. A ventilation duct is placed within the interior volume of the housing beneath the stairs, extending from an intake aperture positioned at the bottom of the housing to an outlet aperture disposed at the open upper end. A fan may be installed within the ventilation duct for carrying air from the intake to the output. Additionally, one or more of the stairs may include drawers installed within the riser of the stair. In some embodiments, shelves and cavities for appliances are formed within one or more of the sidewalls, offering economical storage without requiring additional space.
