Installing architectural elements IE columns are a way to bestow grandeur, or an air of formality, reverence, and ha for ones surroundings. If your looking for a quiet place to read, or review documents having columns quiets the room down. When people enter they become respectful of the area. Installing columns in a formal dining room is saying to the guests that bar room manners are not welcome, and this is not a picnic ground, so put on your good behavior.
If your looking for a light hearted atmosphere to dine with children this is not the room for columns.
Columns make a person take note of their surroundings that something has in the past, present, and/or near future will be happening in this place.
Going back to theses homes I have installed these columns, It bring me back to the meeting that I had attended in these rooms over the years.
Installing cheap columns or ones that are improperly built cheapens the room, which sends a massage to the people coming in seeing them actually ignore the fact columns are there, even thought they have to step around them as they walk through the house.
