William D. Alexander House, Historic house in Provo, United States.

The William D. Alexander House is a residential building in Provo with distinctive wooden framework where horizontal and vertical sticks frame windows, doors, and upper-story dormers. The upper level features wall shingling and decorative elements, while the lower structure displays the formal geometric patterns typical of Stick Style design.

William Denton Alexander, a contractor and builder, erected the house in 1891. It was added to the National Register of Historic Places and designated a Provo Historic Landmark on March 7, 1996. Alexander served on the Provo City School Board, as justice of the peace, and as a city councilman, and was an LDS missionary in the Hawaiian Islands from 1878 to 1881.

The house is now occupied by Encircle, a 501(c)(3) non-profit LGBTQ+ resource and community center serving youth, parents and queer adults. Its turquoise exterior has been repainted in different colors over the years, and the building remains well preserved.

The house stands at 91 West 200 South in Provo, a short walk from the city center. It now serves as Encircle, an LGBTQ+ resource and community center, so the building is in active use rather than open as a museum; visitors should check with the organization before planning a look at the exterior.

This residence is the only documented example of Stick Style architecture in the entire state of Utah, making it a special place for those interested in architectural history. This rarity gives the building particular importance beyond its local significance.
