Enter through the opulent lobby of the Osborne cooperative and its magnificent turn-of-the-century details with its marble, mosaics, gilded surfaces and leaded glass. The Tiffany glass was created by Louis Comfort Tiffany and is reputed to be Tiffany's first decorating job. Welcome to 4B, the meticulously renovated crown jewel of the legendary Osborne Apartments. Renovated by AD 100 designers Carrier and Company, and featured in AD and multiple design publications, this stunning move-in ready four bedroom’s Gilded Age details set the stage for a lifestyle of unparalleled luxury and sophistication. The sun-drenched living room has restored mahogany paneling, elaborately carved doorways and windows, and a very special bay window with Tiffany Studio-created leaded glass transoms. Additional details include plaster crown moldings, oak parquet floors,~14 foot ceilings, and one of five wood-burning fireplaces. Adjacent, the parlor room evokes the grandeur of bygone days with a spectacular framed oak doorway with pocket doors and period hardware. Here is another of the five wood-burning fireplaces, this one with a playful marble surround. The living room, library and dining room all have raised and fielded paneling that accentuate the architectural beauty of the space. Wall coverings include restored original wainscoting and bespoke Ralph Lauren fabrics. Original details include pocket doors, leaded glass transoms, gorgeous oak flooring, original, restored plantation shutters, and much more. In a word: exquisite. These sunny, south-facing spaces offer a serene retreat amidst the busy urban landscape. Before the kitchen is a grand formal dining room with lacquered wainscoted walls and built-in window seats. The eat-in kitchen has a soaring ~14’ ceiling, a rolling ladder that’s both practical and a fun design element, plus a custom central island that provides a pop of color and functions as the kitchen’s main gathering space. Incredible storage is available in the custom quartersawn oak cabinets; top-of-the-line appliances are integrated with custom panels.
