Not all homes have a dining room. These days there aren’t so many people and families that like to all sit down and have dinner together each day given the busy schedule and the commodity of dining, let’s say, in front of the living room TV for example.
But this doesn’t mean that a dining room becomes unnecessary. Instead of trying to eliminate it you should try to think how to make it more suitable for your lifestyle. If you’re not the traditional type then find some other idea or concept around which to organize this space.
