Opinions wanted on box beams in great room
We're building a new home and considering installing box beams over the great room. The beams would be around 5-6" deep (and about the same width). The resulting coffers will be crowned all around. If we decide not to add these, we'll just crown the perimeter of the room. The ceilings are 9' high. We'll mount a semi-flush fixture in the center of the central coffer and can lights in the center of the others.
There's an adjacent kitchen/nook area that will be crowned around the perimeter but won't have any beams. There's an actual structural beam separating the great room from the nook/kitchen area.
We think the room will look good with or without the beams, so we're looking for helpful opinions to push us one way or the other. On the pro side, the room is fairly large and we think the beams will help to partition/break it up a bit. Also we just think they will look pretty cool. On the con side, we usually see beams like these in more formal rooms, and we're worried how the smooth mill work will look next to the textured ceiling (which has a brocade finish).
Any thoughts appreciated.
