In some instances we like to design cabinets that go wall-to-wall. However, in this case, the angled junction of the fireplace mantel and hearth would have made a wall-to-wall unit awkward. The new piece is wrapped with the same base molding as the rest of the room, and the whole piece is crowned with the dentil molding profile used on the mantel. These elements tie it beautifully to the room.
The central area of the cabinet will house the flat-screen TV, and the electronic components are tucked into a cabinet below. The unit still affords a great deal of space for toys, games, videos, etc, and the open shelving on the side will be for decorative items. These side niches are glass shelves with an appropriate piece of wood trim adhered to the front edge, and they're lit with a tiny, elegant LED light fixture, about the size of a 50-cent piece.
It makes a beautiful and very functional addition to this room! The type of "furniture" that will be there as long as the house stands!
