The upper cabinets between the kitchen and the den were removed today. Amazing how much this has lightened and brightened the space, but now the question is: should I keep going? We've left the opening to the studs. I may take that entire portion of the wall down because on the other side of that is the formal dining room, which has a large picture window. This will bring even more light into the room, but at the expense of "deformalizing" the dining room.
