According to the publisher, Cardbird Door is composed of both single and double weight corrugated cardboard boxes and fragments that were printed with screenprint and offset lithography to match the originals used by the artist. The hand-fabricated components were reinforced with wooden substructures that added rigidity and strength before they were applied to a standard 30" hollow core door. The door faces were covered with brown Kraft paper impregnated with casein glue and water. The printed reinforced components were secured to the door with contact cement. The doors were equipped with invisible Soss hinges and Schlage lock assemblies. Special fabricated aluminum hardware was constructed to support the hand-fashioned screenprinted oak doorknobs.
