For more storage you might want to look into build a wardrobe closet. A wardrobe closet helps you not only have more storage, but gives you a place to keep your clothes organized.
Frame the Walls In
Once you know where you want to place the wardrobe closet, you will have to begin by framing in the walls. 2x4 studs are the most common materials used for framing and are placed 16 inches on center. You can build the walls on the floor, or if you using an existing area, just build the frame on the wall.
Add Shelves and Cabinets
After the frame has been built, either by scratch framing (framed on the ground and lifted into place) or by building directly onto existing walls, it is time to add the shelves and cabinets. Plywood, or other types of hardwood can be used here.
Add Walls and Trim
If there are exposed areas of your wardrobe closet then you will be closing them in with wallboard or drywall. Cut the drywall to size and hang to the exposed 2x4 studs. Tape and mud compound the cracks and screw holes, sand, and then paint. Add trim to the top and bottom for a finished touch.
Finish Inside, Door
Depending on what you want on the inside of the closet, paint or stain the shelves and cabinets. Add a folding or sliding door and you are done with your wardrobe closet.
