The concept varies in popularity by the decade. Homes built in one era will have defined rooms for cooking, dining, family time, and guests. A house build twenty or thirty years on either side may have an “open” or “flowing” concept with all of the above areas separated by furniture or half-walls to give an open or airy feel rather than the privacy of defined rooms.
Either concept works. Think of great historical houses and shrink them for defined rooms. What mother hasn’t longed to have the children out of sight and hearing for at least a short time?
When you have limited floor space you have fewer options. The home below, consisting of two rooms with a central fireplace, is an example of the open concept.
In one space we have: bedroom (lower left), playroom, dining room, and kitchen. The mantle holds a clock with room for medium-sized storage jars. The kitchen cupboard the the right of the fireplace contains dishes. Many homes of this era (1830’s) also had a wood box inside, but in this case, I believe it was just outside the door.
Curious as to location? This is the birthplace/early childhood home of Mark Twain. I believe the house he died in had more than two rooms.
