Straddling the fireplace are two wood pieces offering a contrast in materials. On one side is a fruitwood burl stereo cabinet topped by a Himalayan jasper sculpture by Pan Qiqun. On the other is a walnut “Z” console, whose legs loosely form that letter.

Among the accessories on the table is a circular glass sculpture by Arizona artist Peggy Pettigrew Stewart, which continues the geometric theme beginning in the foyer with the mosaic-tile-floor pattern that repeats throughout.

A polished white-bronze Margaret Lamp by Lyle and Umbach also adds to the sculptural lines.

The focal point of this room, however, is the artwork, “Ganges River Delta, India” by Valley artist Stuart Anthony Black. A dramatic mixing of satellite image photography and artistry, Black’s piece depicts, in oranges, whites and earth tones, a 100-square-mile region during the monsoon season when the Ganges River roils huge amounts of sediment into the sea.

“I take raw satellite measurements of infrared light being reflected and emitted from the Earth’s surface and merge this data to create abstract, pseudo-color interpretations of the world’s most spectacular geographical features,” says the artist, whose Pangea Gallery is in Scottsdale. A signature design gesture, Sonia wrapped a pillow in a Hermès scarf she found in the Madison Avenue store and picked up some of the colors in the Black artwork; this rests on, and contrasts with, the Knoll sofa.

This flow continues in the adjacent dining room, which boasts a “Verona 92” credenza bearing a swirling design. Contemporary Italian designer Luca Scacchetti designed the combination birch, cherry, mahogany and walnut end piece. A round glass table sits on a contemporary-style round wool rug, and the cylindrical lighting fixture reinforces this circularity.

“We chose this artsy credenza because it is elegant and playful at the same time,” Sonia says. “That is what I want the interiors I design for my home and elsewhere to be: stylish, elegant, and yet not too serious.”

Smiling, she points to the oil painting above the credenza: “Cuatro Mujeres En Silencio” (“Four Women in Silence”) by Hilario Olivia from Santo Domingo, Dominican Republic. “I loved the title and the art because I am always talking and I thought it was hysterical that I liked a painting that was the quiet, silent type.”
