This spacious, sun-flooded corner apartment is found at 310 West End Avenue, a sought-after prewar cooperative in the heart of Manhattan's Upper West Side. Designed by noted American architect Emery Roth, who designed many of New York City's finest Pre-War apartment buildings and hotels, the fifteen story structure was built in 1925 and converted to a cooperative in 1988.     The apartment enjoys wonderful light through many over-sized west- and north-facing windows and features 9'3" ceilings and beautiful original wood floors. A gracious entry foyer (7'8" x 13'3") leads to an expansive living/dining room (13'10" x 23'6") with 3 west-facing windows and a closet. The versatile layout includes a master bedroom (15' x 11') with an en-suite windowed master bath and a walk-in closet. A second bedroom (15' x 13') wraps the corner of West Seventy Fifth Street and boasts a rarely available second en-suite master bath. A staff/guest bedroom (11'6 x 6'3") includes a windowed en-suite bath and a Bosch washer/dryer. The chef's kitchen (6'3" x 11'9") affords abundant storage in custom-designed cabinets, granite counters and a large west-facing window.     310 West End Avenue is a well-maintained, full-service building with 24-hour attended doorman service, a resident building superintendent, laundry facility and bicycle storage area. The superb residential location is convenient to neighborhood schools, shops, restaurants and public transportation. The building is located only one block from Riverside Park and its playgrounds.
