Its NRHP nomination states that the building's significance rests in its fine Arts and Crafts interior, which stands out in southern Louisiana:In a very general sense the thousands upon thousands of bungalows in the region reflect the influence of the Arts and Crafts movement.

Most bungalows in southern Louisiana have plain interiors with perhaps a brick mantel or a few oak cabinets.

By contrast, the interiors at the Narrows feature paneled wainscotting, double framed ceilings, balustrade screens, and a very elaborately articulated staircase.

None of the comparable examples known to the State Historic Preservation Office have the degree of openness and spatial complexity found at the Narrows.

This single aspect places the Narrows in the vanguard of open planning as it was developing in the early twentieth century.
