What a transformation in the former ''garage'' at this fantastic home sitting on approx. 3.73 acres in Lake Serene! You may remember seeing this one scooped up last year, and sellers are relocating out of state, but not before making this house even more fabulous! What was a former LARGE garage (39x26) is now a stunning guest house! Downstairs features a large, open living room, kitchenette/bar, and full bath, while the upstairs boasts a large bedroom and great storage space, adding 1,014 square feet of additional living space! This addition offers flexibility, upgraded features, and fine finishings. The main house has been improved upon, as well, with brand new top-of-the-line appliances, the addition of a second large master closet with access from the triple garage (if you come in late or messy), an iron railing around the front porch, removal of all carpet and installation of LVP, and several other upgrades throughout. The main house features a split plan with 3 bedrooms (one currently being used as an office), 1.5 baths in the secondary wing, and a gorgeous primary bedroom and SUITE of a bathroom off the kitchen. There is a an additional room (or 5th bedroom) upstairs, complete with a full bath. Enjoy views of your private pool from most of the living spaces in the main house, and when you're outside using the pool, you'll really appreciate the brick & wood privacy fencing, TV (with metal awning), and fireplace area, as well as a covered porch and lots of open space for gathering with family and friends. And don't forget the 1/2 bath in the garage for super easy bathroom access without dripping through the interior! The house is perfectly situated on a small hill on the almost 4 acre lot, and the guest house is easily accessed. The guest house has a private, fenced yard, and a lean-to for additional storage in the rear. Such an oasis in the center of Oak Grove, convenient to everything, and smack dab in the middle of the Lake Serene amenities, including clubhouse, swimming, boating, beach, playgrounds, and more.
