About This Property

Stunning contemporary masterpiece on Gifford Lake with lavish amenities and serene surroundings.

Tucked along one of Armonk's most distinguished roads, this lavish contemporary home blends Mediterranean architectural influence with dramatic scale and thoughtful updates. Set on 2.56 private, landscaped acres with tranquil views of Gifford Lake, the residence offers over 7,700 square feet of light-filled living across three expansive levels.

A circular drive and central fountain welcome you to a double-height foyer, where sunlight filters through a barrel-vaulted skylight, and illuminating marble-inlaid floors. The sunken living room, with its carved imported stone fireplace and walls of glass, anchors the main level alongside an entertainer's kitchen outfitted with Sub-Zero, Wolf, and a newly installed Victory range hood. French doors open to a broad lake-facing deck-an ideal setting for gathering or reflection.

The first-floor primary suite occupies a distinct curved wing, offering a fireplace, dual walk-in closets, a spa bath, and an adjoining private study. Upstairs, four oversized bedrooms and two full baths offer flexibility for guests, work, or creative space.

Over the past year, the home has seen a comprehensive series of upgrades-ranging from exterior stucco restoration and full roof resurfacing to deck reinforcement, skylight replacements, a new fuel tank system, and curated landscaping to open up the lake view-reflecting long-term care and thoughtful investment in the property's future.

Located within the Byram Hills Central School District and just minutes from Armonk Square, the Connecticut border, and major commuting routes, 65 Round Hill Road offers a rare combination of architectural character, lifestyle flexibility, and a tranquil lakefront setting-all in one of Westchester's most sought-after communities.
