Townhouse Scale, Penthouse Views This remarkable five-bedroom residence brings together qualities rarely found in a single Manhattan home: the privacy and expansive proportions of a townhouse, the light and views of a penthouse, and multiple levels of private outdoor space. Perched above Columbus Avenue and overlooking the park and grounds of the American Museum of Natural History, the home unfolds across a series of generous living and entertaining spaces. A nearly private elevator opens to a residence of exceptional width, depth, and volume, with soaring ceilings, immense windows, and exposures in multiple directions. At its heart is the extraordinary Great Room. Dramatic yet inviting, it features a distinctive fireplace and broad eastern views over the museum grounds, along West 81st Street to the towers of the Beresford, with the Midtown skyline to the south. Its scale accommodates both intimate evenings and large gatherings with ease. The principal east-facing terrace, located on the top floor, offers a sweeping outlook over the museum grounds to Central Park and beyond. Additional terraces create multiple opportunities for outdoor living, dining, entertaining, and gardening. To the west, the residence rises above the surrounding buildings, revealing the Upper West Side stretching toward the horizon. The primary suite occupies an entire floor, creating a true private retreat with a wall of windows, sweeping views, a generous dressing area, and a sumptuous bath. Each of the four additional bedrooms has its own en suite bathroom, offering unusual privacy for family and guests. Above the primary suite, a newly completed guest or entertainment suite includes a bathroom and kitchenette and is flanked by terraces to the east and west. A well-appointed kitchen, additional living areas, a dedicated laundry room, abundant closets, and substantial storage support the practical rhythms of everyday life. The residence offers the freedom to live expansively: children can play, friends can gather, and dinners and celebrations can unfold seamlessly. Its location places many of the city’s leading schools, restaurants, parks, museums, and cultural institutions close at hand. Its remarkable proportions and flexible configuration offer the next owner an opportunity to preserve what is distinctive or reimagine the interiors for a new generation. Few Manhattan homes combine this degree of privacy, scale, light, outdoor space, and commanding views. With the intimacy of a private house and the city unfolding below, 428 Columbus Avenue presents an Upper West Side living experience that cannot easily be replicated.
