This Manhattan apartment is an interpretation of the work of legendary French designer Francois Catroux. We enlarged the foyer and paneled it with rich red-lacquered walls. The living room and library/den work together as park-view entertaining spaces when double pairs of French doors are opened. We added the antique fireplace to the living room to anchor the space. The former black powder room was paneled to mesh with the formal rooms and lightened in tone. The kitchen was redone with new cabinetry and opens to the family dining area. The master bath was completely gutted and replaced with a soft cream marble with subtle gold veins and a new vanity, and the floors throughout were refinished in a distressed surface to give the impression of age.
