Tucked away on a quiet dead-end street, this four-bedroom, two-bath ranch offers an open floor concept throughout, affordable ownership, and an extraordinary backyard retreat. Start the morning with coffee or tea on the welcoming front deck, a great sitting area framed by mature landscaping.
Inside, vaulted ceilings, wood floors, and oversized windows open up nearly 1,100 square feet of connected living, den, and dining space. A striking double-sided brick fireplace, open to both the living room and den, anchors the main level. The open kitchen features quartz countertops, white cabinetry, Energy Star stainless appliances, a center island, a tile backsplash, and a skylight overhead. The primary suite is on the main level, with a walk-in closet and private bath featuring a double vanity, glass-enclosed shower, and radiant heated flooring. A spiral staircase leads to a 30-foot recreation room with a full bar.
Affordability is built in: the solar panels are owned outright and fully paid off, and paired with Energy Star appliances they keep monthly utility costs low year-round, with no lease or loan transferring to the buyer.
Out back, colorful garden beds and specimen trees surround a stone-edged pond with cascading waterfall and arched footbridge. Expansive paver patios, a covered pavilion, and an outdoor cooking area create an inviting setting for alfresco dining and entertaining. Approximately 3,258 square feet including the finished lower level.
