A thoughtfully renovated two-bedroom, two-bath home with mid-century modern sensibility in one of the Upper West Side's most sought-after cooperatives. Spanning just shy of 1,300 square feet, Residence 5B offers a rare combination of classic prewar scale and custom modern finishes, with exceptional light from multiple exposures. The ample great room features high ceilings, wide-plank hardwood floors, and multiple windows overlooking the city. At the center of the home, a windowed galley kitchen is appointed with warm walnut cabinetry extending floor to ceiling, white quartz countertops, and a professional-grade range. It opens directly to an eat-in dining area with a full wall of built-in storage and a wine refrigerator. A dedicated home office with a built-in desk and cabinetry, complete with a full bathroom with walk-in shower, is generous enough to serve as a third bedroom if desired. The corner primary bedroom enjoys three windows with open treetop views over West End Avenue and the surrounding streetscape, and is served by a walk-in closet and a renovated Calacatta marble bath with a glass-enclosed shower and floating vanity. The second bedroom is generously proportioned with its own walk-in closet. Both bedrooms share access to a second renovated bath. Additional highlights include an in-unit washer/dryer and substantial closet storage throughout. Built in 1927 by Emory Roth, 310 West End Avenue is a full-service co-op with a 24-hour doorman, live-in superintendent, private storage, bike room, and laundry facilities. Pet-friendly and located one block from Riverside Park, with convenient access to playgrounds, bike paths, dog runs, express transportation, neighborhood markets including Fairway and Citarella, and the Upper West Side's dining and retail corridors. >> Assessment: $642.25/month through 2030.
