Five hundred seventy feet of shoreline. You can walk it, all of it, from the three-slip boat dock at the east end to the point where the manicured lawn gives way to wooded trail at the west, and the open water of Geist Reservoir never leaves your sight. The boats are tied and still. The bald eagles that nest on the property are circling somewhere overhead. And the estate behind you, 21,000 square feet of architecture originally built by GunnSmith in 1990 and transformed by Michael Andretti and builder Rob Annee of the Palladium Group into the largest home ever listed on Geist, rises from the shoreline like it grew out of the land itself. Inside, a gas-lit, tree-lined drive delivers you through the gate to the main level, where every gathering space frames the reservoir through walls of glass. The fireside study opens to the estate lounge—bar, billiards, sitting rooms, the kind of flow that makes a Tuesday evening feel like a hosted affair. The primary kitchen is the centerpiece: a 14-foot island, an imported Italian range, dual custom sinks, dual dishwashers, built-in beverage and produce drawers, and a four-bottle WineStation. Steps away, a discreet caterer's kitchen handles large-scale entertaining without breaking the main room's composure. Through the electric screens, the 38-foot heated veranda opens with a stone-framed grilling station and sweeping lake views. The owner's suite shares a double-sided fireplace with the bedroom, its curved walls framing the reservoir through a full wall of windows. A spa bath beneath a glass-tiled barrel ceiling and 650 square feet of closet space complete the retreat. The upper level splits into two wings, one with a loft and two en suite bedrooms, the other a fully independent guest wing with its own kitchen, living room, two en suites, laundry, and garage access. Below, the resort-style walkout level is a world unto itself: a 15-seat bar, a 700-bottle wine cellar, a movie theater, an arcade, a billiards room, a fitness studio, four more bedrooms, five bathrooms, and four exterior exits that open directly to the grounds. And the grounds deliver everything: a 50-foot heated gunite pool with waterfalls, a waterslide, fire features, and a jacuzzi. A heated and cooled children's play cottage. Multiple patios and terraces. A 2023 carriage house with two 900-square-foot apartments, each with kitchen, bedroom, living room, laundry, and two-car garage. And 5,500 square feet of climate-controlled garage space with twelve-plus bays for a serious collection. By evening, you're on the veranda, the reservoir going flat and golden, the dock quiet below, and the Andretti Estate doing what it was built to do, making the rest of the world feel like it's happening somewhere else entirely.
