The A. T. Averill House is a historic building located in Cedar Rapids, Iowa, United States. Local architects Sidney Smith and William A. Fulkerson designed this 21⁄2-story, brick Late Victorian home. It was completed in 1886 for farm implement dealer Arthur Tappan Averill. This is a more restrained version of the High Victorian style. The house features a truncated hip roof, a 21⁄2-story polygonal bay, and a rectangular tower set on the diagonal. The carriage house/barn behind the house is of a similar design, but older. The house was listed on the National Register of Historic Places in 1978.
