Architectural Masterpiece Overlooking King Lake At $9.95 Million

550 Blue Heron Way, Milton, GA 30004

Set upon a private 2.21-acre peninsula on the shimmering shores of King Lake, Havenstone stands as a rare masterpiece of architectural excellence and artisan craftsmanship. This is not just a home—it’s a landmark estate, a statement of vision and artistry that transcends generations. Spanning more than 22,000 square feet, this extraordinary residence combines old-world materials, global design influences, and advanced modern engineering in a way that few properties in American real estate ever achieve.

From the first glimpse, it’s clear that Havenstone is unlike any other house currently listed for sale. Its façade, crafted from hand-chiseled Leuders limestone, was constructed by master masons using stone sourced exclusively from a single Texas quarry. Every line, texture, and contour speaks of patience, precision, and pride in craftsmanship. Old-growth cedar beams from British Columbia define both the interior and exterior framework, creating a sense of strength and warmth that anchors the property in timeless natural beauty.

The use of authentic materials continues throughout the home, with ten-inch-wide, hand-scraped walnut flooring underfoot and 19th-century reclaimed French terracotta lending color and depth to the living spaces. Even the doors tell a story—each one custom-carved from Andean walnut and finished with Fiddes Old World wax, offering an unmistakable touch of artistry and authenticity.

Upon entering, you are welcomed into a great room that instantly captures the imagination. Towering cedar beams draw the eye upward toward the vaulted ceiling, while a two-story stone fireplace commands attention as the heart of the home. The burnished plaster walls reflect the warm glow of natural light, giving the entire space a soft, inviting radiance. This is a home designed to both impress and embrace—a place where elegance meets intimacy in perfect harmony.

For those who love to entertain, the chef’s kitchen is a true showpiece. Custom walnut cabinetry frames every surface, while an ILVE Majestic range, a striking copper range hood, and a wood-burning pizza oven bring professional-grade function and Old World romance to the space. Every detail has been thoughtfully considered—from the hand-selected hardware to the integrated storage and open flow that connects seamlessly to the great room. It’s a kitchen made not only for cooking but for gathering, laughing, and creating memories.

The primary suite offers a private sanctuary within this grand estate. Centered around a riverstone fireplace, the room exudes serenity and sophistication. The adjoining spa-style bath is a retreat in itself, with a sculpted soaking tub set in Picasso granite, an Aquatic whirlpool, and a glass-enclosed steam shower that feels more like a luxury spa than a private bathroom. The careful blending of textures—stone, wood, and glass—creates an environment that’s both grounding and indulgent.

On the upper levels, the artistry continues. A floating staircase of hand-forged iron and bronze leads to a fourth-floor loft apartment, complete with its own full kitchen, den, and sleeping loft. Accessible by elevator, this space is ideal for guests, extended family, or private work and creative use. The flexibility and thoughtfulness of the design ensure that this house not only inspires awe but also supports a modern lifestyle with ease.

Beneath the main levels, the lower floor has been fully framed and plumbed for future expansion—an opportunity for the new owner to customize the estate even further. Plans include space for a home theater, bar, gym, safe room, and wine cellar, allowing the next chapter of Havenstone to be written according to the buyer’s vision. It’s an example of how this home, though complete in its beauty, continues to offer endless potential.

Stepping outside, the grandeur of the property reaches an entirely new level. Over 6,000 square feet of outdoor living space invites both grand entertaining and quiet reflection. The multi-tiered pool complex is a private resort in itself, featuring a swim-up bar, a gentle lazy river with push current, and a grotto illuminated by phosphorescent rock formations. There’s a diving basin, a natural hot springs spa, and cascading water features that lead toward koi ponds and the estate’s private dock on King Lake. Every detail has been curated to create an outdoor experience as remarkable as the interior.

For those who appreciate craftsmanship on every level, even the motor court tells a story. Constructed from historic Erie Canal cobblestones, it serves as both a functional entry and a piece of living history—one more testament to the artistry that defines this estate. The combination of texture, material, and history gives the property a sense of permanence that few modern homes achieve.

Technology and comfort have not been overlooked. A full Crestron smart automation system manages lighting, temperature, entertainment, and security throughout the house. Radiant heat flooring ensures year-round comfort, and a commercial-grade fire suppression system offers the highest level of safety. Every modern convenience is seamlessly integrated into the home’s classical design, allowing the owner to enjoy the beauty of a bygone era with all the ease of modern living.

As a real estate offering, Havenstone stands in a league of its own. Located just minutes from Alpharetta City Center, Avalon, and top-rated golf and dining, the property offers privacy without isolation. The gated peninsula ensures peace and security, while proximity to the city keeps every convenience within easy reach. For the discerning buyer, this estate represents not only a place to live but an opportunity to own an architectural legacy—an heirloom property designed to endure for generations.

Every once in a while, a home comes along that redefines what luxury means. Havenstone does exactly that. It’s a rare example of a house where every beam, every stone, and every finish tells a story of passion, precision, and purpose. It’s a property built not just to impress, but to inspire.

For realtors representing high-end homes or buyers seeking something truly extraordinary, Havenstone represents the pinnacle of craftsmanship and design. It’s more than a house for sale—it’s an experience, a work of art, and a place where history and innovation coexist effortlessly.

Owning Havenstone means owning a piece of architectural heritage, a true masterpiece built for modern life yet steeped in timeless artistry. In the world of elite real estate, opportunities like this come along once in a generation. For those who demand the exceptional, this estate isn’t just a home—it’s a statement. A living legacy, waiting to welcome its next custodian.
