The windowless, “bonus” room is an all-too-common feature in Manhattan apartments, but a welcome challenge for us. For this featureless, dark, interior space, we chose to pump up the volume with bold color, sumptuous upholstery and custom lighting and art. Taking the building’s Art Deco style as a jumping off point, we designed furniture and lighting whose streamlined curves and industrial chic vibe were common to the era. Walls in Benjamin Moore’s million dollar red envelop and enliven the room, and commissioned artwork and a button-framed mirror bring light and movement. With renewed purpose as a swank media room, this previously troublesome space became the vibrant heart of the home.
