This mint condition, high floor 3 bedroom duplex apartment with +/- 3,400 square feet was gut renovated and rebuilt with the highest quality workmanship and materials. Located in one of Park Avenue's most desirable prewar buildings on the south-west corner of 76th Street, the apartment has views to the north from its French doors and Juliette balcony and west to the beautiful tower of the Carlyle Hotel. It features ceilings just shy of 10 feet, central air conditioning, an usually grand and loft-like living room spanning over 50 feet and a gracious staircase crowned by a large skylight. Prewar details abound including working fireplaces in both the formal dining room and master bedroom suite, elegant ceiling moldings and exquisite millwork. The large and carefully designed chef's kitchen features a vented professional stove and large center island plus plenty of counter space to prep for the grandest entertaining, a walk-through pantry and wet bar with wine refrigerator, an additional dishwasher and icemaker. The guest bedroom on this floor is presently designed as a spacious home office and has an adjacent full bathroom which also acts as the apartment's powder room. Upstairs is a welcoming landing which leads to an enormous master bedroom (originally 2 individual bedrooms) with 2 exposures spanning almost 27 feet and featuring 2 large walk-in closets, a stylish master bathroom with double sinks and a spa-like shower with its own water pressure pump to power the shower's numerous jets. Completing the upper level is another large bedroom with full bath, 2 walk-in closets and large windows facing west. The staff in 830 Park Avenue prides itself on first-class, hotel-like service. Built in 1912, the building features a grand walkway to the entrance and provides full time doormen, full time elevator men, a resident manager, private basement storage and a bike room. Pets are welcome and there is a 2.5% flip tax paid by the purchaser. Call, text or email me today to see what sets 11/12B apart from all the other offerings on Park Avenue!
