Decorating the interior of a small living room requires you to consider the space available so that the room when completed looks airy, bright and cheerful. In modern day homes, the high cost of real estate has led to rooms in apartments being smaller and this in turn restricts the sort of designs that you can execute for the living room.
So whether your interior design is modern or contemporary you need to keep in mind the area available and come up with an interior design that makes the best use of materials and colors and allows the final effect to be still be one of space and lightness.
Treatments to windows should not be bulky and use huge pelmets, jambs or sills that take up space. Heavy furnishings for a window in a living room that has restricted space could have the effect of making the room look smaller. Using blinds with the thinnest possible slats would help to give a feeling of space.
Furniture in small living rooms should be minimal and multifunctional. Floor space occupied by the furniture needs to be restricted so that the living room area looks as if it has enough circulation area. This can be done easily by seeing that the supports for the furniture occupy very little space on the ground. Open spaces below furniture can actually help to create the feeling of openness and space which is so important for small rooms.
