This renovated Park Avenue home has been completely reimagined to blend timeless prewar elegance with modern sophistication. Thoughtful design highlights classic architectural details-10-foot ceilings, exquisite moldings, and a decorative fireplace-while introducing contemporary luxuries including wide-plank hardwood floors, an open chef's kitchen, and a versatile den. Located in one of Park Avenue's most prestigious prewar cooperatives, the home is designed for gracious entertaining. From the semi-private landing, a large foyer sets the tone of elegance and leads into a nearly 30-foot living/dining room with oversized windows that flood the space with natural light and frame the beautiful Park Avenue treetops. A mirrored marble bar enhances the dining area, creating a refined setting for gatherings. The windowed eat-in kitchen features abundant counter and cabinet space, a large walk-in pantry, top-of-the-line appliances, and an oversized island with breakfast bar that flows seamlessly into the den-perfect for casual dining or relaxed entertaining. A staff room/home office, powder room, and washer/dryer complete this wing. A separate bedroom corridor ensures privacy. Two secondary bedrooms with large windows share a marble bathroom. The corner primary suite is a serene retreat, entered through a lacquered dressing room with custom cabinetry. The bedroom enjoys bright eastern and southern exposures overlooking lush townhouse gardens, and includes a windowed marble ensuite bath.
