Bathed in southern light on a high floor of a Rosario Candela–designed Park Avenue co-op, this double living room is a study in quiet opulence and effortless grandeur. Original plaster moldings and a stately fireplace remain untouched, while layers of creamy linen drapery, pale oak herringbone floors, and a vast custom silk-wool rug create an enveloping sense of calm. Tailored sofas in soft performance bouclé face one another across a suite of low, ebonized-oak tables, inviting long conversations, and a pair of sculptural 1940s armchairs reupholstered in smoky mauve mohair add a note of understated drama. Warm bronze sconces glow against the ivory walls, and every piece—down to the barely-there sheer curtains—feels chosen not to impress, but to disappear, leaving only the architecture, the light, and the timeless comfort of a home that finally feels like home.
