The Unitarian Universalist Fellowship of Dubuque purchased its church building in the early 2000s. The Carpenter Gothic style building was originally constructed for the German Methodist Episcopal Church in 1885. Over the years, the church building was substantially altered. The most drastic exterior alteration was removal of the belfry sometime in the 1950s-1960s.

In 2019, the congregation began exploring restoration of the building. Work began on the restoration in the fall of 2021. Exterior restoration was completed on the masonry, chimney, wood shingles on the roof and siding, and wood windows. A new Yankee gutter system with copper sheathing and downspouts was installed. The replicated belfry was built off-site, then installed in the fall of 2022.

Inside, the main floor had settled and was severely compromised.  A new steel support structure was installed. In the east wing, a modern drop ceiling was removed to expose the original hand-painted vaulted ceiling, which was conserved for future restoration. An accessible lift and unisex restroom were installed on the main floor. The original wainscot was restored. The lower level was completely renovated.

The total cost of the project was $1.6 million. It utilized private donations, State Historic Tax Credits, and state grants. This project is a highly visible project in the Jackson Park neighborhood, one of the most economically disadvantaged neighborhoods in Dubuque. The complete restoration of this building signals to the community that investment into the neighborhood is important.
