The massing, the fenestration, and the use of arches are characteristic of Richardsonian Romanesque. The house was razed in 1923 and the materials bought by Major George Oakley Totten, Jr., a prominent Washington architect. In 1925, Totten reconstructed the house at 2633 16th Street NW. Of four Washington buildings designed by the firm of H.H. Richardson, the Warder-Totten house is the only surviving structure.
At the rear of the building, the entrance to Totten's original house still remains: the door and windows are embellished, with Neo-classical motifs. The red tile saddleback roof has ornamental copper work along the cornice line. The roof of the tower is capped by an ornamental finial. The original decorative cresting along the top ridge of the roof has disappeared. The roof above the arcade on the west facade of the southwest wing has been changed from its original overhang, and one chimney to the south of the tower has been removed. The only other major change to the front facade is the closing of the entrance under the building and the replacement of the solid wall in front by an arcaded wall which extends 15 feet beyond the building to the south and allows for a drive in front of the house.
