Majestically set on 13-plus acres, this spectacular mid-century by renowned Madison Avenue architects Edelbaum & Webster, boasts a jaw-dropping juxtaposition of modern design and bucolic surround. Experience the intimacy of the compound - the melding of steel, brick and glass, the soaring prow of the exterior, and a pool that takes center stage at dusk with the beauty of the Hunterdon Hills illuminated in the backdrop. Inspired by Frank Lloyd Wright and built in 1958 using a steel truss system, 10 Spring Hill is an architectural masterpiece that exhibits signature attributes - outdoor living, expanses of glass, exposed structural elements, sleek lines, minimal trim and ornament, and intentional angles. Expansive main level offers an awe-inspiring, open-air atrium entry leading to the living area with wood-burning fireplace, three beds, two full/two half baths and deck with sweeping views. Lower level offers a fourth bedroom, full bath, rec space, and separate entry. Additional features include: four-car garage, double-glazed window walls, superior mechanicals, solar, generator and more. Extensive renovations have been critical in restoring the original integrity. The farm-assessed grounds consist of a secluded poolscape and specimen trees - all with exceptional landscape and lighting design. Nearby quaint towns, shopping, fine dining, farmers markets and outdoor recreation- only 50 miles to NYC. Whether you're seeking a serene retreat or a statement home for entertaining, this breathtaking property is not to be missed.
