Residential designs coordinate the interiors of home which is always a matter of balancing aesthetic and function, so we need to consider the primary function of a residence: it’s a place where people live. This means that the residential designs need to be comfortable and usable. It is where you relax, cook and eat. It may be where you entertain your close friends or small group of guests. The residential designs need to ensure that the colors, lighting, furniture and general layout meet these needs.  In other words, the interior needs to be livable.
