This is a great Dining Room! I love the idea of family gathered around a round table. You do not see round tables often in a Formal Dining Room. (I love everything.the furniture, flooring, light fixture, window treatment, and color on the walls).
Decorating with dark paint doesn't mean you'll end up with a room of Stygian gloom. In fact the very opposite. Used properly drama and atmosphere await. Like this living room with large antique mirrors.
