When I was a child my folks would take me along as they visited one of Dad's co-workers who was also a great friend. Dad's friend had built a house that was filled with marvels. For instance it had a glass brick foyer wall in which a number of the glass bricks actually held goldfish. But one of the things that captured my parents' imagination and admiration was the free-standing, movable partitions. I don't know how many of them were portable, but at minimum the partition between the kitchen and the living room/dining room could be moved to allow whomever was cooking to be able to converse with guests. I believe, now that I think of it, that a couple of other partitions could be moved, shrinking another room to make the living room/dining room more spacious.

I don't have any idea as to how the partitions were constructed, (I was only about 5 at the time,) but
these look interesting and are not particularly expensive. Just a thought...
