Represented by Joel Woelfle and Allen Williams of Berkshire Hathaway HomeServices Indiana Realty, The Andretti Estate stands as a singular vision of craftsmanship, sophistication, and serenity. Once home to Michael Andretti, the legendary race car driver and son of motorsport icon Mario Andretti, this estate carries a legacy of speed and precision. Poised along the scenic shores of Geist Reservoir, this residence redefines what luxury living can mean in the Midwest—an architectural triumph blending privacy, scale, and modern elegance.

A Landmark of Geist Reservoir

Set across 5.23 private acres and boasting 570 feet of shoreline, The Andretti Estate occupies one of the most coveted sites on Geist Reservoir—a 2,000-acre recreational lake located in suburban Indianapolis. Woelfle described it as one of the few remaining estate-sized parcels in the area. “The majority of the shoreline is developed in plated neighborhoods,” he said. “Only a limited number of properties of this size exist, and this one not only has the acreage but the location, privacy, and unobstructed views that make it truly exceptional.”

Woelfle reflected on what makes the property so extraordinary, noting that “it’s extremely rare to find this combination of modern high-end craftsmanship on a private lakefront setting in a large metropolitan area.” Williams echoed the sentiment, adding that the estate’s design and location “create a sense of scale and serenity you simply don’t find anywhere else in the Midwest.”

Those views extend from nearly every room of the residence, where walls of glass capture the interplay of light on the water. Manicured lawns blend into wooded trails, creating an effortless connection between the architecture and the landscape. It’s a rare balance between natural tranquility and resort-style luxury—one that few properties achieve with this level of refinement.

A 3-Year Transformation

The 21,000-plus-square-foot residence is the result of a meticulous reimagining. Beginning in 2017, the original structure was partially demolished and then expanded and reconstructed over three years. “The owners did a magnificent job of developing areas for everyday enjoyment, entertainment, and guest quarters,” Woelfle said. “The decor offers a variety of environments throughout the property, and each one has its own personality while maintaining harmony with the whole.”

Williams agreed that the renovation was remarkable in both vision and execution. “The estate was expanded and refined with incredible attention to detail,” he recalled. “The owners managed to blend architecture, style, sophistication, and comfort into one seamless experience. Whether you’re in the main residence, walking the grounds, or visiting the carriage house, every element feels intentional and connected.” The result is a home that merges grandeur with intimacy. Vast open spaces invite gathering and celebration, while quiet retreats throughout the residence offer balance and calm.

Built for Performance

Behind its elegance lies an advanced network of modern systems. Williams explained that the home’s smart tech automation allows for efficient management of various systems. “Whether you're in Indiana or out of state, you can control everything from lighting and audio to fireplaces, HVAC, security, and even the main gate. It gives you true peace of mind and complete control.”

Furthermore, Williams noted that technology wasn’t simply added for convenience—it was integrated as an art form. “The lighting, in particular, was something special,” he said. “It was layered and thoughtful, from the illuminated staircases and bar to the subtle lighting under cabinetry and even inside the closets. It transformed the atmosphere throughout the day, making the home feel alive.”

The estate’s 5,500-square-foot climate-controlled garage was built with the same precision as the rest of the residence. With more than a dozen bays, built-in cabinetry, and direct access to both the guest and carriage wings, it offers functionality and prestige in equal measure. “It was purposefully designed for the collector and enthusiast,” Woelfle said. “Every inch was planned to balance practicality with presentation.”

The owner’s wing is its own sight to behold. Framed by sweeping waterfront views, the suite features a reading retreat with a built-in coffee bar, a double-sided fireplace, and a spa-inspired bathroom resting beneath a glass-tiled barrel ceiling. Williams said the scale and flow of the suite were unlike anything he’d seen. “The size of it catches you off guard,” he reflected. “You walk through an anteroom that leads into a cozy retreat, and the way it connects the bedroom and spa bathroom creates this continuous sense of calm. My favorite feature is the curved wall of glass—it’s both dramatic and peaceful, exactly what a primary suite should be.”

The suite also includes two expansive closets that provide organization and ease for everyday living, embodying what Woelfle described as “effortless luxury.”

Engineered for Comfort

In a home of this magnitude, guest accommodations are more than an afterthought—they’re an extension of the estate’s ethos. The 1,700-square-foot guest wing offers a complete living experience with a great room, full kitchen, and two bedroom suites, each with a private bath. “The guest wing was designed with independence and comfort in mind,” Woelfle said. “It mirrors the quality and craftsmanship of the main residence, allowing visitors to experience the estate with a true sense of hospitality.”

In 2023, the property expanded further with the addition of a carriage house near the gated entrance. Each of its two 900-square-foot apartments includes a full kitchen, living room, bedroom, and two-car garage. “The carriage house was built to complement the main residence, not compete with it,” Williams explained. “It’s perfect for staff, long-term guests, or even security housing, and because it’s slightly set apart from the main home, it offers both convenience and privacy.”

Entertaining Without Boundaries

For moments of leisure and celebration, the lower level redefines what it means to entertain at home. With a 15-seat bar, 700-bottle wine cellar, arcade, billiards area, fitness center, theater, and four themed bedrooms, it’s as vibrant as it is luxurious.

“The lower level gives you the feeling of being on vacation,” Woelfle said. “There’s no need to fly anywhere—you just take the elevator down one level. The glass walls open right up to the pool, waterfalls, lake, and boat dock areas. It connects seamlessly to the outdoors.”

Williams described it as “the ultimate entertainment space,” noting how effortlessly the design balanced energy and warmth. “Whether it’s a family gathering or a corporate event, the space handles it beautifully,” he said. “Once you’re down there, it feels like a private club, but one that still feels like home.”

The Art of Living Well

Outside, the estate unfolds into a resort-worthy landscape. Manicured lawns give way to wooded trails and open water views, while a 50-foot gunite pool with waterfalls, fire features, and a jacuzzi serves as the centerpiece for outdoor living. Multiple patios, a heated veranda, and a three-slip boat dock complete the scene. For younger guests, a children’s play cottage—complete with heating and air conditioning—adds a whimsical touch.

Williams said that the grounds reflected the same intentionality as the interiors. “Every area, from the patios to the waterline, was designed for both beauty and practicality,” he explained. “It’s the kind of property that inspires you to slow down and really live.”

A Once-in-a-Lifetime Offering

“The first time I drove through the gates, down the gas-lantern-lined driveway, and up to the residence, I knew it was special," recalled Williams. "Walking through all three levels and seeing the wooded and open-water views, I was completely blown away. And then I started noticing the little things; the craftsmanship, the hidden details most people wouldn't even think about. Even the door hinges are custom-made works of art. It's the kind of property that keeps surprising you the longer you're there."

When asked to distill the essence of the listing down to three words, agent Joel Woelfle didn't hesitate with his assessment: a “totally unique property."
