About this home

A rare modernist residence designed by noted architect George Nemeny, with interiors by pioneering architect Debora Reiser. Featured in House & Garden shortly after construction, this spectacular, lovingly maintained modern work of art is situated on five private estate acres in the heart of Matinecock, less than 1.5 miles from downtown Locust Valley. The home was harmoniously designed around the historic formal gardens of the former J.D. Lyons estate, originally planned by the renowned firm Delano & Aldrich. The owner, a botanist, further enhanced the grounds with arboretum-quality specimen plantings, creating a truly magical, one-of-a-kind landscape. A striking outdoor sculpture is positioned at the edge of a sweeping grassland meadow garden framed by tranquil walking paths. Further enriching the property's provenance is the historic "Piping Rock," a geological landmark tied to local Matinecock Native American lore. Fully intact, the interiors showcase soaring 19-foot ceilings and expansive walls of glass overlooking the grounds. Floor-to-ceiling sliding glass doors in every room flood the space with natural light, treating the seasonal changes outdoors as living art. The main living spaces are conveniently configured on a single level, complemented by a cozy library perched above the dining room and accessed via an elegant spiral staircase. This property represents a unique opportunity to acquire an architecturally significant, undisturbed modernist home and arboretum-like garden, cherished and preserved by its original owners.
