For the first time since the 1960s, this corner Penthouse with wraparound terrace and greenhouse is being offered for sale by the original shareholder who lived happily here for decades. The apartment needs a complete renovation so bring your architect, landscape designer, and your imagination and create your own one-of-a-kind trophy property. Located on a quiet tree-lined block near Riverside Park, this four-room, sun-filled Penthouse is perched on top of a classic pre-war cooperative. At the heart of this home is a loft-like living room with nearly 10 foot ceilings and Terrazzo flooring. A working fireplace is flanked on either side by French doors leading to a greenhouse resting on the south terrace where you can grow sunflowers, roses, and rhododendrons year-round in your secret garden in the sky. A pair of large glass doors leads to a huge 28'9 x 16 west terrace with a peek of the Hudson River that is perfect for sunset dinner parties and grand entertaining. The bedroom is located in the rear of the apartment and offers privacy and terrace access through sliding glass doors. There is a den adjacent to the living room with a sun-splashed southern exposure. A windowed kitchen with terrace access (and washer & dryer hookups) and a windowed bathroom complete this remarkable home. 321 West 78th Street has an elegant lobby, 24-hour doormen, live-in superintendent, laundry room, storage room, and is pet-friendly. Enjoy walking in Riverside Park, cycling the riverfront Esplanade, dining at the Boat Basin Cafe, shopping at Zabar's, and concerts at the Beacon Theater. The subway and crosstown bus are just one block away. It's all here in this thriving Upper West Side community. Shown by private appointment only. Flip Tax: 2.5% of the sales price paid by seller.
