A one-of-a-kind mint condition duplex that combines 20-foot coffered ceilings, sun-drenched spaces, and show-stopping century old craftsmanship throughout provides an incomparable living experience in the Upper West Side. The majestic 27'8" x 20' living room, anchored by a massive marble fireplace, is bathed in light from a grand north-facing window complex and an artistic west-facing stained-glass window. This is a rare opportunity to own a room of such scale and drama, ideally suited for both unforgettable entertaining and beautiful contemplation. Flowing from the living room through an impressive archway lies an enormous second living room currently serving as a family den and dining room. A south-facing wall of original stained-glass windows, another colorful west-facing stained glass window and a stunning fireplace mantle create a special space for relaxing and an ideal venue for memorable meals, both grand and intimate. The chef's eat-in kitchen has to be seen to be believed. Two separate entrances lead to 500 square feet of culinary bliss, featuring terra cotta floors, custom wood and leaded glass cabinetry, an eight-burner hooded and vented Wolf stove and double oven, twin sinks, two huge south-facing windows, and the added luxury of a vented space for the washer and dryer. With endless cabinet space and a spacious pantry closet, this kitchen is as functional as it is beautiful, offering everything a cooking aficionado could desire. A sliding mirrored door can be used to separate the kitchen area from the eat-in section, ensuring peace and quiet while meals are prepared. Upstairs, the breathtaking primary suite is a sanctuary with south and west exposures, flooding the room with natural light. The windowed en-suite bath is beautifully designed with elegant details including precious glass tiles and custom fixtures. Two additional bedrooms, each with generous closet space and southern exposure, ensconce children or guests in cozy comfort. The home's second level is completed with a striking marble hallway full bathroom, a unique home office, multiple hallway closets, and an ample mezzanine area. Bonus Feature: A detached ground-floor locked room with windows and closets offers myriad possibilities-a luxurious private gym, spacious home office, extra den, or voluminous storage area, all with direct lobby access, further distinguishing this property from anything in the market. Set in a full-service boutique prewar co-op, the building features a full-time elevator operator, new gym, manicured roof garden, and additional basement storage.
