Description

Enormous Sun-Flooded Pre-War 4-Bedroom

First offering of this remarkable sunny and elegant gigantic four bedroom, pre-World-War I home rich with historic charm. Originally the Sponsor's trophy residence, now a re-sale, this classic layout is perfect for both everyday living and entertaining, boasting soaring 10' ceilings, tremendous light, and unobstructed views.

A semi-private landing leads into a large and gracious formal entry foyer, and spacious side-by-side living and dining rooms spanning over 40-feet with spectacular southern views to Hudson Yards and beyond. It is unusual to get so much light, and such expansive views, in a pre-war home: Residence 9A drips with prewar details including quarter-sawn-oak herringbone floors, original decorative fireplace mantles, high ceilings, French doors, and crown & baseboard moldings throughout. The massive windowed kitchen has a large dining area and butler's pantry. The gracious original prewar layout allows for a private bedroom wing, separated by a long corridor perfect for displaying art, and there are capacious closets throughout.

Situated in the heart of the Upper West Side on a quiet double-wide tree-lined block, The Royal Summit is a full-service cooperative built in 1915 by the architectural firm of Mulliken and Moeller and incorporated in 1981. Boasting one of the most stunning and ornate lobbies in the city, the cooperative comprises approximately 67 homes, housed in two identical and adjoining buildings (310 & 320 West 86th St) for maximum privacy and intimacy in each small building.
The Royal Summit, which is in superb physical and financial condition, is pet friendly, has a 24-hour doorman, live-in superintendent, various porters and staff on duty, storage, a bike room, and central laundry facilities in the basement. An added bonus is a tranquil resident's patio garden in the back of the building.

Right next to Riverside Park, located on a landmarked double-wide block with no city bus traffic, this home is close to all of the best dining, shopping, and entertainment. The Hudson River Waterfront Greenway is at your doorstep with dog runs, and jogging & biking trails. Nearby transportation includes the 1, C, B subways and various buses including the 86th Street crosstown. Even though this particularly handsome block is so quiet and serene, you are only 1 block to the 1 train and the 86th Street crosstown bus and all the conveniences Broadway has to offer.
