Dr. Samuel H. Allen House and Carriage House, Victorian mansion at 135 East 200 North, Provo, United States

Dr. Samuel H. Allen House is a brick residence featuring four prominent gables, rusticated stone trim, and ornamental porch work with a multi-colored exterior. The property includes one of Provo's largest historic carriage houses, with its lower level adapted with windows for contemporary use.

Dr. Samuel H. Allen moved to Provo in 1892 and built the house with local workers and materials, running his medical office there until it moved to the Knight Block. In 1903 Samuel R. Thurman, a former Lehi mayor and Utah Supreme Court judge, bought it, then sold it to John W. Taylor, who settled his third wife Nellie Eva Todd there. Taylor's 1915 excommunication forced a sale to Dr. David Westwood, vice-president of Provo General Hospital, whose family left it vacant in the 1940s. Monroe and Shirley Brockbank Paxman bought it in 1952; their grandson Colin Foy purchased it in early 2022.

The house reflects the shift between Queen Anne and Revival styles, a time when successful professionals shaped Provo's residential areas. It shows how wealthy residents expressed their status through architectural choices.

The property sits in a quiet residential area and is visible from the street. Visitors can observe the architectural details from outside, as it remains a private residence.

The two-story carriage house may be the largest building of its kind in Provo, and its lower-level bays were later filled with windows. The main house is among the tallest and largest historic houses in the city, though heavy landscaping partly hides its mass from the street.
