This unique, one-of-a-kind, custom-built gem provides an abundance of features and use opportunities. The 4000 sqft, 3-story home, proudly sits on approx 10 acres of unrestricted, sub-dividable land on beautiful Lake Hartwell. Please note the lake views are limited, the owner has kept the trees in tact. They can be limbed for better views. With a total of 6 bedrooms and 5.5 bathrooms, the home’s main level includes a bedroom, full bathroom, library room with built-ins, living room, dining area, ½ bath and the kitchen which boasts custom cabinets and granite countertops. A screened-in porch extends off the dining area and attaches to the open deck off the living area. The master bedroom on the second level has a full bathroom and its very own screened-in porch that faces the lake off the back of the house. Continue up a set of ladder stairs and enter the magical 360-degree observatory. This adorable little house topper can be used as a sitting room, a small art studio, or simply to wow yourself and guests with stunning views, sunrises and sunsets! Above the heated, cooled and fully insulated 3-car attached garage sits a one-bedroom apartment complete with kitchen, washer/dryer, spacious bedroom and bathroom and a separate central heating and air system. Perfect as an in-law suite or for additional family or guests. Or a rental! In addition, the walk-out basement has been fully finished with a bedroom, full bathroom, media room, storage room, large rec room and, again, it’s very own heating and cooling system. The basement walks out and through the 2-car, lean-to carport and onto the path where an easy walk takes you to the covered 26’ x 14’ boat dock with 24’ x 10’ boat slip set in a tranquil cove which opens up to the big water of the lake! As if this isn’t enough, a new 40’ x 24’, 960 sqft enclosed steel storage barn sits on a concrete slab and can be used to house boats, RVs, a car collection and more. Additional windows, doors, dividers can easily be added to build it out to your heart’s content. Another ADU perhaps? A horse barn? Small business shop? Retreat center? Two additional 40’ x 12’ lean-to carports are attached to either side of this barn. This property could easily become a retreat center, equestrian estate, or, of course, keep it all to yourself as your own private oasis ... Don't miss out on this charming home and rare opportunity to own acreage on Lake Hartwell.
