Property Description

Welcome home to this RARE opportunity on Geist Reservoir. Tucked away on a private cul-de-sac in the prestigious Masthead community, this extraordinary 4-bedroom, 5-bathroom lakefront home offers over 6,190 square feet of luxury living paired with one of the rarest amenities on Geist Reservoir, "a grandfathered-in" boat garage. No longer permitted to be built on the lake, this coveted feature makes this property truly irreplaceable. Designed to maximize breathtaking water views, the home welcomes you with soaring ceilings and dramatic floor-to-ceiling windows that frame the waters of Geist from nearly every angle. Whether you're enjoying your morning coffee in the sunroom, hosting friends in the expansive all-seasons room complete with a built-in indoor gas grill, or unwinding beside the fireplace, every space is designed to bring the outdoors in. The main level offers elegant living spaces, a luxurious primary suite, and seamless flow for both everyday living and entertaining. Upstairs, enjoy your own private movie theater, while the walkout lower level provides additional living and recreation space with direct access to the backyard oasis. Step outside and discover what truly sets this property apart. Spend summer evenings on the rooftop sun deck atop the boat garage, entertaining guests while taking in panoramic views of Geist Reservoir. Launch your boat with ease, relax in the hot tub after a day on the water, shoot hoops on the private half basketball court, or gather with friends across multiple outdoor entertaining spaces designed for unforgettable lakefront living. Complete with a 3-car garage, walkout basement, and endless amenities throughout, this is more than a home; it's a rare piece of Geist history that can never be recreated. Luxury. Lifestyle. Legacy. Welcome to Geist Reservoir living at its finest!
