Things You'll Need
Large rooms in your home may need to serve more than one purpose, such as providing a living space for two teenagers or creating an office space in a bedroom. Yet, you may not want these different spaces to be connected, and building a wall may appear to be your only option in redesigning the room. However, before you invest in the expense of a carpenter, consider constructing your own walls out of cardboard. The cost is significantly less and when you want to alter the room again, the cardboard can be removed from the space.
Measure the area where you want the wall. Measure both the height and width of the space.
Gather the cardboard. Purchase large cardboard sheets from a home improvement store or use large cardboard boxes.
Cut the cardboard with a utility knife. If you are using sheets of cardboard, cut the cardboard based on your measurements. If you are using cardboard boxes, cut off enough of the pieces of the boxes to match the measurements you have taken.
Tape the pieces of the cardboard boxes together using plaster wall seam tape. This type of tape will allow you to paint over the seams from the pieces.
Stand the Walls
Lay the cardboard wall on the floor.
Measure the width of the cardboard and mark off every two feet with a pencil and ruler.
Fold the cardboard like an accordion. At each two-foot mark, fold the cardboard lengthwise. With each fold, turn the cardboard in the opposite direction of the fold before. Stand your wall upright.
Paint the wall with acrylic paints and a paintbrush if you want a solid color wall.
Draw images on your wall with a pencil and paint them in with acrylic paints if you want designs on your wall.
Paint the cardboard a solid color, cut out shapes from pieces of cardboard and attach them to the wall with glue if you want to add dimensions to your wall. Once the glue dries, paint the shapes with acrylic paints.
If you would prefer to have a solid wall, rather than an accordion style wall, build a frame for your wall out of 2-by-4 wood, and attach the cardboard to the frame with a staple gun. Connect the wood frame to the existing walls with screws and a screwdriver.
