About This Home

139 Sebago Lake Drive

Stately all-brick residence in prestigious Diamond Run, perfectly positioned to capture sweeping, breathtaking views of the #6 fairway. Impeccably maintained and exceptionally upgraded, this 4-bedroom, 4.5-bath home offers an elevated level of craftsmanship, architectural detail and thoughtful design throughout. A dramatic two-story covered entry welcomes you, complemented by professionally landscaped grounds, an exposed aggregate driveway and walkway, and an oversized three-car attached garage. Inside, rich hickory hardwood floors, beautiful millwork and pocket doors throughout create a sophisticated yet comfortable atmosphere. The gourmet kitchen is truly a chef’s kiss, featuring Sub-Zero, Dacor and other high-end appliances, generous prep and storage space, and a sun-filled breakfast room overlooking the spectacular golf-course setting. The kitchen is equipped with an induction cooktop and is already plumbed for gas, offering the flexibility to convert to a gas cooktop if desired. A separate caterer’s kitchen with an additional refrigerator and dishwasher makes entertaining on any scale effortless. The formal dining room is designed for a special dining experience, complete with a butler’s pantry and classic butler’s door, adding both function and timeless elegance. The family room is equally impressive, featuring a handsome box-beam ceiling, fireplace and French doors opening directly to the patio, seamlessly connecting indoor and outdoor living while showcasing the sweeping fairway views. One of the home’s most dramatic architectural features is the grand two-story library, with custom built-in bookcases and a soaring wall of windows framed by plantation shutters. An additional office/workspace offers a built-in workstation and direct access to the patio, providing exceptional flexibility for working from home. The posh primary suite is a private retreat, complete with its own fireplace, luxurious bath and generous closet space. A second spacious en-suite bedroom offers exceptional privacy along with large closets, making it ideal for family or guests. Two additional generously sized bedrooms feature large closets and share a well-appointed Jack-and-Jill bath. A conveniently located second-floor laundry completes this thoughtfully designed bedroom level. The expansive finished lower level provides another dimension of living and entertaining space with a gym, sauna, full bath, additional flex room and an abundance of storage. Outdoors, professionally landscaped grounds and a covered veranda create an extraordinary extension of the home—ideal for alfresco dining, entertaining or simply relaxing while taking in the sweeping views of the #6 fairway. Additional highlights include a newer roof, two new HVAC systems and meticulous care throughout. Exceptionally upgraded, beautifully elevated and pristine in every detail, this is a home where quality is evident at every turn. Simply move in and begin enjoying the Diamond Run lifestyle.
