Allow more light to enter the living area by using light curtains. If possible semi transparent curtains that are just enough to reduce glare that may be caused because of sunshine, instead of using heavy looking "valances" use basic 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. There is one more different method of defining the perception of the living room (or any interior space) and that's the empty volume put aside after all the furniture as well as other accessories have been fitted. Because anything in our living world is usually "relative". The perceived volume is always relative to the empty volume that may be normally used for circulation. The more empty volume you get, the bigger the room will look.
