In the old police headquarters building on Centre Street in Manhattan was once the radio room. Renovations revealed 16 steel beams that supported a magnificent dome, which lights the living and dining area during the day and offers a place in which to hide architectural lighting fixtures. Uli+friends made the perimeter glow at night to define the volume. The lighting fades toward the center, creating a three-dimensional shape. The glossy white paint on the lower wall bounces light into the room and anchors the perimeter.
