To give a concrete example you could choose to keep a contemporary theme with plenty of black and white colors modern materials and a few pops of bright blue. With this in mind a glass TV stand a glossy black living room set a chrome and glass coffee table and some bright blue accessories or modern art on the wall could look fantastic.
Choose a focal point. Choosing a focal point in your living room space is important as you want to accentuate the best features of the room. A window is a great feature in any living room space both for the view it may have and also the light that it lets in. If this is your focal point arrange the furniture near by and make sure both you and your guests can enjoy the view/sunlight. Other focal points in the room include an entertainment unit or a fireplace. These areas in the room should be accentuated as well.
Almost everyone loves a spacious room and if your room is small then you just have to do something about it. You can make your room appear bigger by placing mirrors in strategic positions. Doing this will increase the width and the breadth of your living room from the reflection.
