Mason House, near Dallas, North Carolina, 1938, by Frances Benjamin Johnston, via
Library of Congress Prints and Photographs Division.
A narrow porch for a narrow house. I think those are cannas at the bases of the columns.
This picture was published in The Early Architecture of North Carolina by Johnston and Thomas Tileston Waterman in 1941, but I can’t find out anything else about the building.

The symmetry and two front doors make me think of the Shakers.
It’s a really pleasing looking duplex house, but each side much have been cramped. It looks like there was one room on each floor, plus the back kitchens.
