A triumph of architectural artistry, Havenstone is a rare and irreplaceable estate, meticulously constructed with craftsmanship and material integrity nearly impossible to replicate. Set on a private peninsula lot overlooking King Lake—Milton’s largest and most prestigious private body of water—this estate is not merely a residence but a living testament to centuries-old techniques, globally sourced rare materials and an unrelenting commitment to perfection. From foundation to finishing details, every inch reflects an uncompromising dedication to authenticity. The façade, composed of hand-chiseled Leuders limestone, was sourced from a single Texas quarry and individually set by master artisans. The architectural framework integrates old-growth cedar beams from British Columbia, structurally and aesthetically uniting the home’s grand interior with its expansive outdoor living spaces. Inside, the residence reveals extraordinary detail, with hand-forged iron and bronze elements seamlessly woven into its design, including a sculptural floating staircase. The interior doors, crafted from rare Andean walnut, are finished with Fiddes Old World wax. Flooring throughout consists of ten-inch-wide, 12-to-16-foot-long American walnut planks, hand-scraped and beveled to create an enduring patina, while reclaimed 19th-century French terracotta and burnished European plaster walls further enrich the home’s authentic, timeworn aesthetic. The great room, a stunning convergence of engineering and artistry, is framed by soaring cedar beams and anchored by a two-story fieldstone fireplace. The chef’s kitchen is an unparalleled showcase of functional elegance, featuring character-grade walnut cabinetry, a hand-hammered copper range hood, an ILve Majestic Italian range, dual Bosch dishwashers and an Italian wood-burning pizza oven integrated into a structure of reclaimed timber. Hand-forged copper sinks, blacksmith-crafted lighting fixtures and custom bronze hardware demonstrate painstaking attention to bespoke detail. The primary suite is a sanctuary unto itself, featuring a hand-selected riverstone fireplace, private garden access and a spa-inspired bath with a Kohler Aquatic massaging whirlpool tub, Picasso granite vanities and an integrated steam shower. Designed for flexibility and privacy, the estate also includes a self-contained fourth-floor loft apartment with a full kitchen, private den, sleeping loft and elevator access—ideal for multi-generational living or extended guest stays. The structurally complete terrace level awaits final customization and was envisioned as a luxurious entertainment space with a home theater, bar, gym, safe room and wine cellar. Expanding the estate’s livable footprint, over 6,000 square feet of outdoor space is anchored by a world-class aquatic environment. A multi-tiered pool experience features a swim-up bar, underground grotto embedded with phosphorescent glow rocks, a lazy river with a functional push current, a diving basin and a natural hot springs-inspired spa. Every water feature, from cascading streams to koi ponds, was designed with geological precision, seamlessly integrating into the landscape to create a resort-caliber environment. Technological sophistication is woven throughout, with a Crestron Whole-House Automation System, commercial-grade fire suppression and a hydronic radiant heat flooring system engineered by a Montana specialist. Even the motor court tells a story, crafted from historic cobblestones reclaimed from 19th-century Erie Canal streets. The estate’s private dock provides direct access to King Lake, offering an unmatched lifestyle of serenity, recreation and exclusivity. Located minutes from Alpharetta City Center, Avalon and championship golf courses, Havenstone is a singular offering—an estate of such architectural and material integrity that it stands as a legacy property, impossible to replicate and designed to endure for generations.
