The style known as Contemporary actually appeared in architect-designed homes as early as the fifties, continuing in the height of popularity during the sixties and early seventies. The fresh, open style remains relevant and favored to this day. Common characteristics include simple, clean lines with large windows devoid of decorative trim, flat or gabled roofs, asymmetrical shapes, and open floor plans. Metals, the color white, and basic, unfussy features are common to the style. Contemporary exteriors are usually stucco, stone, brick or wood.
