The A. P. Johnson House, also known as Campbell Residence, is a Frank Lloyd Wright-designed Prairie School home that was constructed in Delavan, Wisconsin, USA, in 1905.

[1] The Johnson house sits on a 6-acre lot on the south shore of Lake Delavan, on a small wooded hill with a view of the water.

[3] Characteristic elements of Prairie Style are the low-pitched hip roofs with wide eaves, the raised central mass, bands of casement windows, and horizontal siding.

The house is clad in horizontal tongue-and-groove wood siding, which Wright often used on small cottages.

William Storrer writes: It is said that when Wright, approaching on horseback via the dirt driveway to supervise final stages of work on this Prairie style tongue-and-groove-sided house, saw it painted white, he rode away, never to return.
