Thank you for the suggestions. Putting a concave mirror is something that I could do. However, I don't know where to put it, as there's a window in that area. Please see attached floor plan. Our unit would have the mirror image of this floor plan, so the living and dining room would be on the left side.
Am I correct when I said that it's the SW sector that's missing? Do you have any suggestions on how we could ensure that we're following the feng shui principles in this condo unit?
