Located in Brooklyn, New York, Box/Box is a small apartment all decorated with Ping-Pong Balls. According to the architect, Box/Box was conceived as “an accelerated design/build experiment and was completed within a two-month period at a cost of less than $100 per square foot. A gradient of 25,000 spheres clad the walls, moving from dark to light as they meet the illuminated grid of the ceiling, made of translucent panels that reveal a hidden grid of spheres when backlit. This luminous ceiling, the skylight and the facing mirrors on opposite walls brighten and expand the room to create an illusory space that appears more expansive than actual size.”
