The interior of the FLAT is focused around a MEDIUM central hallway serving as the main avenue of traffic and entrance area to the adjacent rooms. The hallway flows into a large, wide staircase that provides the main means of egress from the entertainment area of the house to the private rooms on the second floor. Four formal rooms with sixteen foot ceilings, pocket doors, fireplaces and tall windows form the main block of the building. The bedrooms have been decorated to approximate the subtler paint colors.

As you enter through the front door on the east facade, you pass into a grand hallway of the building. The wallpaper is Anglo-Japanese design with Roman and Greek themes in the frieze on the ceilings and walls. The predominant colors are dark with tan and gold highlights, creating an interesting contrast to the original interior trim painting of ashen pinks, tans, pale blues and black detailing. This combination of colors is repeated throughout both floors of the house. The tall, heavy, varnished wood doors have as the top panel, colored glass panes of amber, blue and pink, in a geometric design. On either side of the main doors are smaller, longer versions of the colored glass windows. The doors and small windows have molded surrounds of painted wood with bulls-eye cornerblocks and decorative accents on the door surrounds and on the baseboard. The door knobs, plates, and hinges are brass with raised Eastlake style ornament.
