A Stylish Spin on a Traditional New York Apartment

"I wanted to have a library before that notion becomes extinct," says Kedigian, "but the shell had to feel contemporary and fun." Solution? A vibrant custom palette in a Fine Paints of Europe Brilliant finish. Curtains of Clarence House Elettra flank a sofa in Scalamandré's Variegation herringbone. A Louis XV fauteuil (a gift from Kedigian's grandmother) retains its original blue velvet, and a neoclassical side chair is updated with Glant Liquid Leather.

Striking a balance between intimate and formal, the dining/music room features walls upholstered in subtle Chelsea Editions Diamonds outlined with ebony-painted trim (black warmed with a dab of brown). "I needed a softness here to diffuse the visual 'noise' of the high-gloss rooms on either side of this one, but the dark trim still conveys the strength of the architecture," Kedigian says. A set of 19th-century chairs dressed in Schumacher's Shock Wave cozies up to a gently worn velvet banquette with P.H. Dorcic bullion fringe and pillows in Holland & Sherry and Dye-Namix fabrics. He used gold paint to dress up the wood table base by Mecox Gardens. The display cabinets have a faux-limestone finish.

"I never start on the decorative aspects of a space until I've settled on a solid furniture plan," Kedigian says. He designed the living room sofa and upholstered it in the same Chelsea Editions Diamonds that he used in the dining room, but in another colorway. The club chair is covered in Clarence House's Neisha Crosland Fleuret Chevron and the corner banquette in Lee Jofa's Spectrum Velvet, which provides "a fireside amphitheater for views out the French doors."

Bronze antiquities — a Pompeian dancing faun and a Greco-Roman head — rest on a Parzinger console. The rococo mirror, a housewarming gift from a client, came tied with a red bow.

In the living room, an art project Kedigian painted in architecture school hangs above a vintage Parzinger campaign chair. New moldings conjure Beaux Arts grandeur.

Of the clock in his master bath, the designer says: "Bathrooms, like kitchens, should be decorated as comfortably as other rooms, so they feel part of the house."

Kedigian left the bed hangings, in Schumacher's Maiandros stripe, unlined to enjoy their Greek key motif in positive and negative. Walls are Benjamin Moore Aura in Putnam Ivory.
