RARE BIRD, INDEED.Q: Can you wait another 36 years? Yes - 1988 is the last time this jewel of a home has been offered. And a jewel it is as there is nothing of its size anywhere else on Riverside Drive. This penthouse is literally architectural gold atop the choice south-west corner of the building.Five well-designed and spacious rooms are bathed in light all day long from massive single panel windows (unobstructed as a/c is thru-wall). The main rooms face south, the living room has a wood-burning fireplace, and the dining room enjoys the southwest corner. There are two bedrooms, two full baths, a washer/dryer, a spacious well-appointed kitchen, along with high ceilings and hardwood floors. The penthouse is alone on its piece of the building's top floor - no other apartment shares its private elevator vestibule.And - crowning it all - is a 100-foot-long wrap terrace, perfectly balanced running south and west. Fully equipped with light and an auto-irrigation system, the terrace is an oasis of plants and flowers. The open views south and west are equal to the very best of Riverside Drive. You will lose yourself in this garden in thesky.Constructed in 1922, 370 Riverside Drive is a 15-story brick, limestone, and terra cotta Georgian Revival residential building located in the Morningside Heights Historic District. This full-service building has long been highly regarded for its strong physical and financial management, and has thrived without a flip tax (there is a capital contribution in place of $487 per month). It includes a landscaped Roof Deck with spectacular views of the Hudson River and the surrounding area, a large Community Room, Children's Playroom, Bike Storage, Central Laundry and storage units. The building is pet-friendly, and on a case-by-case basis will consider pied-a-terres.Located in a particularly rustic stretch of Riverside Park and the Hudson River Waterfront Greenway, it will have a special appeal to those who enjoy walking, jogging, biking, or a trip to the dog run. It is in close proximity to Columbia University and the vibrant culturally rich community that surrounds it, excellent shopping and transportation, and numerous highly regarded public and private schools. The 1 train, M104 and cross town bus are just two blocks away, and the coveted M5 bus line is just across the street.Can you really wait another 36 years?
