Under Stair Storage Closet Wall.
When I lived with my parents I did it in a two-story house, and I remember that under the stairs they decided to build a small under stair storage closet to store tools. The square meters under the staircase are usually "dead", so I decided to look for some ideas so you can bring it to life and add a new place inside your house. In the steep staircase is a perfect space under it, there will be this piece of furniture, at the entrance of the house, the decoration of this area has as starting point of the design, the rail of the staircase, metallic in very strong blue color.
