Description

If space is what you're after, then look no further than this sprawling Upper East Side home, just a block from Central Park. Apartment 4CD at 40 East 84th Street is a fully renovated 4 Bedroom plus den (or 5th bedroom), staff room and 6.5 bathroom home in a prime location. The gracious layout is perfect for how we live today, with separate areas of the apartment for different uses. The elegant foyer serves as the hub at the center with a wing for the master bedroom and den/office, another wing for the three secondary bedrooms, an enormous fully renovated kitchen and staff room with large capacity washer/dryer, and a grand living room that seamlessly connects to a separate formal dining room. The entrance hall was recently redesigned with a separate powder room that has custom Gracie wallpaper, marble sink and floors. Off this lovely gallery are the newly renovated living room and formal dining room. The beautiful millwork in the dining room allows for discreet and significant china, glass and linen storage. The enormous eat-in kitchen has marble countertops, a Sub-Zero refrigerator, six-burner Wolf range with oven, second Wolf wall oven and broiler, Sub-Zero wine fridge, and new Miele dishwasher. The center marble-top island with additional cold storage drawers, is perfect for a casual “breakfast bar” meal, but additional banquet seating with large kitchen table allows for a larger meal in the kitchen for 10+ people. The adjacent staff room has its own en suite full bathroom as well as full size, fully vented LG washer and dryer. Once in the master bedroom wing, the apartment boasts not only an enormous bedroom suite that has its own sitting area, but also two large “his and her” separate dressing room closets that have already been built out and custom fitted. The ensuite master bathroom has a large glass enclosed step-in shower and double vanity sinks. Down the hall from the master bedroom wing is a large den/office with its own newly renovated full bathroom. This den/office can double as a fifth bedroom, or guestroom. On the opposite side of the apartment, are the three secondary bedrooms, each with its own renovated bathroom. Each of these bedrooms has beautifully grand proportions, and have either north/street exposures or south, sunny open courtyard views The elegant millwork, electronic shades, custom moldings, newly installed wide plank, solid oak, sound-proofed flooring, HVAC units with thermostats, and top-of-the-line appliances all contribute to this lovely home's inviting feel. The thoughtful renovation was designed to accommodate the high standard of living demanded by today's discerning buyers. 40 East 84th Street is a pet friendly, low maintenance, well-established co-op with a 24-hour doorman, storage, live-in super, bike room and garage that's mere steps from museums, Central Park, and all of the convenient boutiques, grocery stores, cafés, and coffee shops that have come to typify life in the east 80s. The building is also just a stone's throw from all major transportation. There is a 3% flip tax paid by the buyer.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
