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.
Whilst maintaining themes throughout your space, make sure that you do not add too many, and also that there are not too many dominant pieces in any given space. By their very nature, the quality of a natural wood finish can be very alluring and eye-catching, so avoid using tons of this material everywhere.
