Interior walls stop short of the ceiling or are eliminated altogether, permitting air and light to flow freely. Built-in furnishings and freestanding pieces visually separate space. Broad bands of casement windows and French doors further erase boundaries, extending space beyond the house into nature. Windows joined at right angles make corners disappear. Continuous stripes of wood trim, placed just below the ceiling and along window and door tops.
Views are open from room to room, conveying a sense of freedom and movement.
Most ready-made furniture was incompatible with Prairie architecture. So Prairie School architects designed their own, striving for graceful, simple pieces suitable for informal living. Using the same materials and ornamental detailing for both house and furnishings lent integrity to the whole and guaranteed artistic harmony. Prairie School furniture, like the architecture, was carefully crafted to emphasize a tranquil horizontal line. Table tops and other horizontal planes were cantilevered beyond their supports and often rested on massive legs, creating the illusion that the furnishings, like the house itself, were grounded to the site.
