There is a precedent for this double-door in a ready-made built by a carpenter according to instructions laid out by Marcel Duchamp in 1927. We adopted the same basic element and designed its structural and ornamental details to fit the standard parts of Shotgun House construction and decoration easily found in a Home Depot. These include standard 2x4 studs, door frames, baseboard, chair rail, and crown molding. Typically called molding, these elements are not just decorative; they are also, of course, practical. They help span the gaps and bridge expansion joints necessary in typical light frame construction. The doorjamb detail is one place where the elastic qualities and flexible nature of domestic molding is of great benefit. The molding wraps the corner of the jamb and also folds in the corner of the room, making the double-door detail possible.
