James Park House, Knoxville

Located in Knoxville, the James Park House is a significant historical structure. The L-shaped building stands two-and-a-half stories high, with a contemporary service wing situated at the back. Governor John Sevier laid the foundation in the 1790s, and Knoxville merchant and mayor James Park (1770–1853) completed the house in 1812. It is the second-oldest building in Downtown Knoxville, after the Blount Mansion.

To restore the house, Claussen utilized old photographs and architectural research. They added a picket fence around the property, reconstructed the Victorian-style front porch, rebuilt the front stairs, and reshaped the chimneys. Additionally, they restored an arched fireplace in the basement that had a design similar to the one in the Craighead-Jackson House.

The floors of the modern service wing have been painted with various historical maps of Knoxville. One restroom features a ceiling-to-floor safe, while another was modeled after the Red Sage restaurant's restroom in Washington, D.C.

The James Park House is registered on the National Register of Historic Places and serves as the headquarters for Gulf and Ohio Railways.
