What was originally used as a parlor at the landing of the grand staircase was transformed into a retreat for a creative soul. “We allowed the architectural elements, most notably the stained columns, to create the outer boundary of our space and used the windows and doors leading to the balcony as an open backdrop,” says Marjorie Slovack. Airy draperies and a warm brown grass-cloth wallcovering lighten the area, accentuating the darker wood throughout. The ceiling was painted to evoke an expansive and luminous sky, creating height, delineating the space from the hallway, and lending an artful dimension. “We added modern furnishings with reflective surfaces that add light and intrigue,” says Slovack. A mix of floor treatments—leather and wool shearling—and comfortable oversize pieces also grace the open room.
