Allow more light to enter the family area by using light curtains. Instead of using heavy looking "valances" use simple and easy if possible semi transparent curtains that are adequate to reduce glare that could be caused because of sunshine. Use brighter color schemes commonly known as "hot" color schemes. These create a very good reflection and transmission of natural as well as artificial light inside the living room. There may be one more different procedure for defining the perception of the living room (or any interior space) and that's the empty volume put aside after all the furniture along with other accessories have been fitted. Because anything in your living world is always "relative". The perceived volume is always relative to the empty volume that is certainly normally used for circulation. The more empty volume you get, the bigger the room will look.
