By using light curtains, allow more light to enter the family area. If possible semi transparent curtains that are only enough to reduce glare that could be caused because of sunlight, instead of using heavy looking "valances" use simple and. Use brighter color schemes commonly known as "hot" color schemes. These create a very good transmission and reflection of natural as well as artificial light inside the living room. You can find one more different approach to defining the perception of the living room (or any interior space) and that's the empty volume put aside after all the furniture together with other accessories have been fitted.

The more empty volume you get, the bigger the room will look.
