In open floor plans, this is a great room. In closed floor plans, this will be a living room. However, the purpose is still the same, and that is to provide a communal space for family and visitors. The kitchen is likely not an eat-in kitchen. With an open floor plan, you can place a small table (suitable for the size of the apartment) for eating at. With a living room, one may have to sit in chairs or couches.
This room will also be in the front of the residence. When you enter the residence, this will likely be the first room you would enter. From there, you can go to the other rooms in the residence. This room will be large enough to host a couch, a recliner chair, and end tables. If you choose to have a home telephone service in your residence, then the phone will plug into your provider’s ATA, and the ATA will plug into any of the RJ45 jacks. However, I will see that most people will likely have a cellular line. I will see the point of having a home telephone line for those with children that are too young to have their own telephone.
