This is the old City Bank building on East Capitol that has been converted into a private residence. Definitely not in the style of homes on the Hill, but I guess it’s in line with older commercial establishments here. There are actually a lot of old storefronts that have been converted into homes. The architects try to make them look homey, but you can always tell where those store windows used to be. The red house below is different from most of those but still looks to have been some kind of commercial building once upon a time.

NOTE: I changed the image to a closer view that shows some of the formal looking ornamentation on the building.
