A rare opportunity to own a distinguished residence at 101 West 78th Street, also known as The Evelyn, where timeless prewar elegance meets contemporary refinement. Currently configured as a three-bedroom, two-and-one-half-bath home, Residence 4B offers the potential to be gracefully reimagined as a four-bedroom, three-bath layout while preserving its refined design integrity. Bathed in natural light from open east and west exposures, the residence enjoys serene views over the tree-lined museum grounds, creating a tranquil and picturesque backdrop. The expansive great room offers graceful proportions for both entertaining and everyday living, framed by classic architectural detailing. A thoughtful layout accommodates multiple bonus spaces - ideal for a home office, media room, fitness area, or guest suite. The serene primary suite provides a spa-like retreat with radiant-heated floors and an oversized soaking tub. Custom millwork, generous closets, and carefully considered storage enhance both livability and sophistication. Originally designed in 1886 by Emile Gruwe and masterfully reimagined by AD100 designer Stephen Sills, The Evelyn was restored and converted in 2017, seamlessly blending 19th-century architecture with 21st-century luxury. Interiors feature soaring 10'6" ceilings, oversized windows, wide-plank white oak herringbone flooring, and richly detailed finishes that echo the building's prewar heritage while supporting modern living. Residents enjoy a 24-hour attended lobby, fitness center, children's playroom, bicycle storage, and cold storage. Located moments from Central Park and overlooking the American Museum of Natural History and Hayden Planetarium, this bespoke Upper West Side residence offers timeless character, elegant design, and an exceptional lifestyle.
