Basement ceiling. Need to keep access to plumbing so used white washed paneling cut into halves. Attached to ceiling but used screws where we need future access. Trim covers edges of boards. Cut holes for recessed lighting. Love it. Did have cheap looking dropped ceiling this gives 5 extra inches of head room.
A modern version of the look is seen in this Florida bedroom. Keeping the ceiling, barn door, and bathroom vanity the same material creates flow and serenity, while the rustic wood itself is a cool feature.
