Description
Terraced Penthouse Living, a dream of most New Yorkers, is now available on one of the Upper West Side's most beautiful brownstone blocks, just off Riverside Drive. Enter this gracious top floor PreWar home from a semi-private elevator landing and be swept away in old world grandeur.
Through the arched formal entry, immediately noticeable are stunning original features including gorgeous terrazzo floors in the living room and bedroom, and a wood-burning fireplace with its elegant mantel and brick hearth.
The generous proportions of the living room add to the drama of its high ceilings and abundant light from windows facing north and south. Two sets of French doors lead directly to the 300+ square foot terrace, perfect for al fresco living and dining, with eastern views of the Museum of Natural History and the Hudson River to the west.
The modern renovated kitchen offers a Sub-zero refrigerator, Gaggenau oven and cooktop, GE dishwasher, solid wood cabinetry with plenty of storage and workspace, and a windowed doorway to the north terrace.
The bedroom is a wonderful light-filled space large enough for a king-size bed and offers two double closets and a built-in desk and bookshelves spanning the entire width of the room. Architectural plans already exist for a simple and inexpensive renovation creating a second bedroom or home office, subject to board approval. See alternate floorplan.
Built in 1925 and designed by noted architects, Sommerfeld & Sass, 321 West 78th Street is an elegant ten story building of red brick and limestone. It was converted to co-op in 1979 and is 100% owned. Building features include a full-time doorman, live-in super, central laundry, common storage, and bicycle storage. With board approval, the co-op allows up to 75% financing, pets, washer/dryers, and pied-a-terre purchases.
