Los Angeles-based interior designer Mark D. Sikes imbued this Park Avenue, New York apartment with old-world elegance and a wonderful sense of style, yet kept things cheerful, chic and alive for the clients, a couple with young children. The starting point for the colour palette was the de Gournay hand-painted floral wallpaper in the dining room that intermingled shades of robin’s-egg blue, red, lapis and lilac, the colours you will see repeated through out the apartment.
