This is your opportunity to create your dream home in one of the best buildings on the Upper West Side.

Years ago, one of the original bedrooms and its bath, of this one-of-a-kind, sun-flooded "B line", was sold off to the apartment next door. Now there are two large bedrooms and two windowed bathrooms that both face west and offer winter-river views. The third bedroom is off the kitchen and also has its own smaller, en-suite bathroom.

The side-by-side, loft-like, living and dining rooms, face south and enjoy city and side river views as well.

These two very spacious rooms could easily be reworked to create three; dining, living, and library or den.

Other features of this warm and inviting home are its large, windowed, updated, eat-in kitchen, full-size vented, washer/dryer, huge closets, soaring ceilings, and hardwood floors. The building has allowed central A/C.

90 Riverside Drive is an established, pet and pied a Terre friendly co-op with impeccable financials, a roof deck, a high-tech gym, a cool play and basketball room, deeded storage cages, and two bike rooms. The experienced staff of this full-service co-op offers white-glove service including a resident manager, concierge, and doormen.
