About This Home
As of April 2026Beautifully maintained home featuring hardwood flooring throughout the main and upper levels and thoughtful upgrades across all four finished levels.
The main level showcases a bright kitchen with tall cherry KraftMaid® cabinetry, including a generous pantry with convenient rollout drawers, Silestone quartz countertops, and a charming breakfast nook with a large window that fills the space with natural light.
Upstairs, hardwood floors continue through all three bedrooms. A sun tube in the hallway brings in additional natural sunlight, creating a bright and welcoming space. The spacious primary suite offers a large WI closet with Elfa shelving and a beautifully appointed bathroom featuring a walk-in shower and heated flooring. The updated hall bathroom includes a deep soaking tub, along with convenient cedar and linen closets in the hallway.
The lower level provides a cozy family room centered around a brick fireplace with a gas insert, flanked by built-in cabinets and bookcases. This level also includes a versatile fourth bedroom, den, or home office with a built-in desktop and ample cabinetry, an updated full bathroom with shower, and a laundry room with LG top-load washer and Samsung gas dryer.
The fourth level offers a large recreation room along with an expansive utility and storage area featuring gas HVAC and a hybrid electric water heater.
Outdoor living is just as impressive with a 20x20 screened-in porch featuring paving stone flooring, a high ceiling, ceiling fan, and a Hot Springs hot tub—perfect for relaxing or entertaining. The backyard also includes a patio with a natural gas grill and a large, fenced yard backing to open field space for added privacy and views.
