This is a good example of how a great design idea does not have to be expensive, and can produce dramatic and interesting results. We pre-painted all moldings before putting them on the wall. Sometimes people know that they want to achieve balance in a room. This floor plan and space plan was a good example of that. We did achieve balance starting with symmetry.
People often overdo the symmetry, chair right, chair left, lamp on the right, lamp on the left, etc.
Follow the plan for symmetry, and then remember to throw something off to relax the formality and the rigidity of the mirror imaging. Also, I think people to often design their rooms for others, or do the expected thing. They should design for themselves, and be individuals. While it's important to love the piece that you're buying, don't buy it for love alone. Make sure that the piece is appropriate for its intended location and usage.
