The Roy O. Allen House on Marlborough Road is arguably one of the most renowned modern homes in Westchester County and a celebrated icon of mid-century glass architecture worldwide. Featured prominently in Architectural Digest, Dwell, GQ, The New York Times, and TV shows like Fallout and Hunters (Amazon Prime), this 1957 International Style pavilion is a masterwork of design. (In fact, these owners have an established filming location fee with Amazon, Apple & Netflix studios.) Meticulously restored, reimagined, and modernized with the finest materials and amenities, it stands as a testament to architectural excellence. Designed by the esteemed Roy O. Allen of SOM—lead architect of Manhattan's iconic 1 Liberty Plaza—this stunning residence was originally crafted for his own family. Nestled on 1.66 acres of bucolic land, surrounded by old-growth trees, the home offers sweeping seasonal views of the Hudson River from every room. Having undergone two major renovations, the Roy O. Allen House has been elevated to an ultra-luxury standard. A newly reconfigured primary suite now features a breathtaking slabbed calacatta verde bathroom with Waterworks fixtures and an exquisite custom Poliform walk-in closet from Italy, crafted from glass, wood, and leather. Designer details in the suite include upholstered moss-green suede walls and a leathered stone accent wall, paying homage to the home's Mies van der Rohe-inspired design ethos. Additionally, a brand-new king bedroom suite has been created, complete with plush wool Stark carpeting and an en suite Waterworks bathroom clad in Sahara Noir marble, featuring a rain shower. Further enhancing the home's aesthetic are custom Apparatus light fixtures, Buster + Punch metal switches, and Stark carpeting, seamlessly blending high design with timeless modernism. A cinematic tour de force, the home showcases the changing seasons in a way only a masterpiece of glass and light can. While an entertainer's dream, the Roy O. Allen House is also an inspired sanctuary for those seeking an escape—just 39 miles from the rush of the city. Frequent visitors include bald eagles, hawks, osprey and owls, all adding serenity to this tranquil retreat. A viral sensation in architectural and interior design circles, the Roy O. Allen House is truly a once-in-a-lifetime marquee property. #theallenhouse
