That hollow triangle of space beneath your staircase can house more than lint. Claim the square footage for organizing your stuff.
Closet
One of the simplest and most common under-stairs storage solutions, a closet can be lined with shelves and equipped with wire organizers to provide an abundance of organizational space. Include a light fixture in your plans.
Open Shelves
Rather than keep your belongings undercover, line the space beneath your staircase with built-in shelves that provide access from the side of the stairs. Use wicker baskets or canvas bins to corral smaller items.
Drawers
Drawer storage allows full view and access to your belongings in one smooth motion. Accessed from one side of a staircase, drawers can be designed in a variety of depths and widths. Or, build drawers into the risers of one or more steps.
Cabinets
Built-in cabinets can feature solid doors or doors with glass inserts. Use clear glass when you want to keep books and treasures on display, or choose decorative opaque or translucent glass to obscure the contents.
