The sale of the reimagined Kleeberg Residence, an individual New York City landmark, offers a once in a lifetime opportunity to purchase one of the largest and widest single-family residences ever offered in Manhattan. 3 Riverside Drive boasts 26 principal rooms across a gross interior square footage of HOW MUCH square feet with approved plans for 9 bedrooms, 11 bathrooms, 4 half bathrooms, two studies, a staff office, an 83 ft/25 meter marble pool, a partial basketball court, a stadium seating movie theatre and endless other amenities. The house is 37 ft wide, has a soaring 25 ft high double height oval living room and is directly on Riverside Park with sunset views over the park and the Hudson River with tremendous natural light. Originally designed by famed mansion architect CPH Gilbert in the late 19th century, the home will be delivered to the new purchaser with fully approved Landmarks & DOB plans by the acclaimed Italian architect Achille Salvagni. Salvagni is an AD collector top 100 international designer, a member of Elle Dcor's A-List, won Robb Report's 2018 Best of the Best Yacht Interior Designer, won the World Yachts Trophies Award and his custom furniture routinely sells at auction and in premier galleries around the world. Construction has been underway for the better part of five years and much has been accomplished: the full excavation of the sub-grade space is complete and bedrock has been dug out down to 36 feet, the required shoring is complete, interior demolition work is complete and approvals and all permits are issued and approved. The new owner can complete the current project in a seamless manner or has the option to customize to their own liking. Current approved plans deliver only the highest level of luxury amenities and finish to the home. Approved amenities more typically found in a large, full-service building include a half Olympic sized lap pool (25 meters), an onyx-walled hot tub, a 22 ft high basketball court, a stadium-style cinema, multiple terraces including a panoramic rooftop terrace, radiant heating throughout, a side-walk and stoop snow and ice melting system, a generator, bullet proof windows on the lower front of the house, a full security and building management system and laundry/trash chutes throughout the home. The residence is marked by its unparalleled scale and unique footprint, with fully expressed width at 37 ft and depth built to the full extent of the lot on the ground floor and most of the lot up to the roof. This provides tremendous scale to the home including a primary suite spanning 2,200 square feet with large and separate "his and her" bathrooms and closets and a powder room. The primary closet is two stories with its own interior stair-case and spans nearly 1000 square feet. The park-front positioning of the home as well as rarely found windows on the 2nd-5th floors in the middle room of the floor allow for all daylight and views of the Hudson River, exceedingly rare for such a grand mansion. Nearly all townhouses look across the street at another townhouse - not a park and the river like 3 Riverside Drive. The exterior of the home is built in French Renaissance Revival style, rich with historical elements including carved limestone ornaments, gabled dormers, and a wide projected bay. It proudly and prominently sits between 72nd and 73rd Streets on Riverside Drive, located proximally to world class culture, restaurants, parks, and transportation.
