Living rooms or living/family rooms are the largest area of the residential structure and often were called grate rooms in older generations of residential buildings. The purpose of this space within the home was gathering of family members and or friends. Because of this purpose there is a very specific geometry for living room design. The size here is the primary factor, then comes the shape which must accommodate the activities which we expect in this space. In addition, the design of a living room must be done with the kitchen and dining room in mind, and how these three elements work together as a unified whole.
