In addition to paint you should change out all of the window dressings. When you step into any home one of the biggest elements that ages the interior design is the window dressings. Change out not only the color, but the style. Today curtains and blinds are affordable options and are available in many different styles and colors. Make sure that your new window dressings compliment the color of the paint on the walls. You can choose something in the same color family, or you can add another touch of color by opting for something altogether different.
Another way to change the interior design of your home is to add throw rugs or runners on the stairs. You will want to choose more modern pieces than you currently have. In addition to rugs, you may think about replacing your flooring altogether. If you have old dingy carpet you are automatically aging your interior design. Pull out worn carpet and consider replacing it with new carpet or even tile. Tile and wood floors are really popular right now and the products on the market make these flooring options really easy to care for.
If you are not sure what to do to change the look and feel of your home, why not bring in a professional who deals with interior design? They may give you some great ideas that you can do on your own or with their help. Sometimes the changes need not even be all that drastic and they will change your home instantly!
