Portable Lamp for Living Room, Henry J. Allen Residence

Frank Lloyd Wright's design for a portable lamp combines geometric precision with organic form. The top diagram shows the shade's radial structure—a semicircle divided into triangular segments—establishing the mathematical basis for the conical shade below. The rendered elevation reveals Wright's attention to material and craft: a golden pleated silk shade sits atop a cylindrical stem and weighted base. Specifications note the shade measures 20 inches in diameter with an overall height of 31 inches. This lamp exemplifies Wright's philosophy of designing complete interior environments, where furnishings extend architectural principles into domestic space. The lamp was created for the Allen House, a Prairie School masterpiece in Wichita, Kansas.
