Applying light colored paint to your walls can make a small room appear larger. Pale-colored walls and furniture makes a small room look larger. Using dark colors would only play into the visual of making your current room look much smaller.
It is important that your window treatments complement the rest of the decor in a room. If your blinds do not match, they will stick out like a sore thumb and take away from your overall presentation. Make sure the window treatments match each other and the other decor.
When you design your home, be sure to get all of your flooring to match on one level. You can either use a flooring that complements the other rooms or you can use that same flooring. This will create a natural flow from each room. Not all of your living room furniture has to directly face the TV. Create a place where people can talk by placing some chairs away from the viewing area. This will be a nice place to relax and converse with a friend over a cup of tea.
Do not waste any space in the home. If there are a few bare walls in your space, think about putting up a painting or some photographs to enhance them. By doing this, your room will definitely have a personality and your home will certainly feel more livable. Try putting together a collection of artwork. A collection is at least three of something that are of the same kind. Three statues or even antiques that have a common theme are a great start for a collection. Three or more pieces are sufficient to make up a collection. Group collections together for an interesting look that will serve as a great conversation piece.
