A remaining jewel of The Astor family, 235 West 75th Street is a striking block front trio of interconnected residential buildings running from the corner of 75th to 76th streets on Broadway. Expanded upon in 1914, the elegant three-tower silhouette offers 98 residences. The exterior is finished in grey brick and crowned by an elaborate decorative cornice. Now elegantly restored into stylish traditional condominium homes by Pembrooke & Ives, the property features a mosaic-detailed lobby, twenty-four-hour concierge, a gym and state-of-the-art interior enhancements. The prewar design details—including ceilings as high as ten feet tall, custom moldings, three-paneled doors and newly installed double-paned bay windows—offer a stylish and versatile canvas.

The Chatsworth, a luxury pre-war co-op conversion built in 1904, is one of the most iconic and prestigious buildings on the Upper West Side in New York City. The 58 spectacular residences include spacious 1-5 bedroom homes, as well as penthouses and townhouses. Standing triumphantly at the base of Riverside Park, this historic and landmarked Beaux-Arts masterpiece has been lovingly upgraded, renovated, and restored to its original grandeur while including every modern amenity and service to meet today’s wants and needs. Newly designed amenities at The Chatsworth include a library and business center off the lobby elegantly appointed with custom stained walnut millwork, a state-of-the-art gym and fitness center, children’s playroom, game room, media screening room, wine tasting room and an outdoor garden. The interiors at The Chatsworth reflect the elegance of the building’s exterior, and have been immaculately redesigned by the renowned firm Pembrooke & Ives. Each unique residence synthesizes pre-war scale and proportion with sophisticated design and meticulous finishes, offering an expansive and gracious floor plan, high ceilings, detailed crown moldings, and white oak herringbone floors throughout.
