It used steel beams and sheet steel floors for fire safety, a method borrowed from marine fabrication and called battledeck design. Its open plan and elevations that follow that plan are described as a prophetic forerunner of modern architecture.","narrative":"Set on a wooded knoll of about two acres facing a ravine, this L-shaped house at 441 Cedar Avenue in Highland Park was built in 1929-30 by Henry Dubin as a functional home for his family. Heavy woods and a deep setback hide it from the street and from the neighboring house. Its exterior is conventional brick and cinder block masonry, topped with a flat roof for sunbathing and ribbon windows that bring light and air to the upper floors. A recessed front door and varied roof levels add interest to the facade. The design follows the family's needs rather than historical style, as in the L-shaped bay window seat that adds seating in the dining room. Steel beams and sheet steel floors, a battledeck system previously used in marine fabrication, were chosen for fire safety. The open plan, with elevations that reflect it, is described as a forerunner of modern architecture. The house remains in residential use and is unaltered.","period_of_significance":null,"architect_builder":"Henry Dubin","architectural_style":"International Style","criteria":[],"status_note":"Condition is rated good and the integrity is marked unaltered.
