Coonley House, Prairie School residence in Riverside, United States.

Coonley House is a Prairie School residence in Riverside, United States, built as several interconnected structures on a spacious plot. The property includes a main living wing, a detached sleeping area, a stable with coach house, and a gardener's cottage.

Wright designed this property between 1908 and 1912 for Avery Coonley and his wife Queene Ferry, who sought a home with open spatial planning. The estate was later designated a National Historic Landmark and is considered an outstanding example of early Prairie architecture.

The name comes from the Coonley family, who commissioned Wright to design a sprawling residence for elevated country living. The windows inside feature geometric patterns that break daylight into shifting colors, giving each room a different mood.

The grounds sit in a quiet part of Riverside and are best reached by car. The different building sections spread across the plot, so walking around involves covering some distance.

A water basin in front of the house mirrors the horizontal lines of the facade and reinforces the sense of broad surfaces. The skylights in the hallway to the second floor are crafted in a handwork tradition and differ stylistically from the other windows.
