Per the NR listing:
One-story hipped-roof Craftsman-style house with 2 interior chimneys, a large hipped dotmer window, a pair of glazed and paneled front doors, and 9/1 sash windows. The hipped porch has Craftsman brick posts with granite caps. The original rear porch has replacement posts and railing. Vinyl covers the walls and eaves. The building was constructed about 1915 as the Lakewood Baptist Church. In 1924 it was sold to a private owner and rebuilt as a duplex. No evidence of its original church appearance remains on the exterior. [1930 CD, interview]
I'm not sure whether the author had additional sources other than interview to state that this is the same building that housed the Lakewood Baptist Church - I'm dubious. James Street doesn't even have listings in the city directories prior to 1924, and the Sanborn maps don't cover the area in 1913. The building appears classically residential and Craftsman, i.e. ~1920s.
As of August 2012, at least the exterior renovation seems to be nearly completed.
