Robust volumes and soft finishes define the well-outfitted kitchen used frequently during entertaining by celebrity and professional chefs. A massive wood-block island, timeless cabinetry by Christopher Peacock in Los Angeles, stainless- steel and glass-front Sub-Zero and Miele appliances, and barstools by Maxine Snider for Holly Hunt add even more iconic appeal. Spans of onyx travertine and hand-scraped walnut floor assembled in a herringbone pattern by Builders Carpet achieve understated embellishment.
