Welcome to 1112 Summitridge! Where you will find timeless Tudor character, exceptional craftsmanship, and a floor plan designed for the way people actually live. This distinctive 5-bedroom, 3-bath residence pairs generous proportions and extensive natural materials with thoughtful upgrades that enhance functionality while preserving the home s architectural warmth. Custom leaded-glass double entry doors open to a foyer finished in genuine Italian marble. Brazilian cherry hardwood enriches the formal living and dining rooms, while large format travertine flows throughout the kitchen, family room, wet bar, downstairs bath, laundry, and hallway. Custom millwork, crown molding, solid-wood details, and built-in cabinetry further distinguish the interiors. At the heart of the home, the extensively remodeled kitchen was expanded approximately 30% from the original builder configuration and features custom Signature cabinetry, granite countertops, a full height tumbled travertine backsplash, illuminated display cabinetry, and an expansive single level peninsula with exceptional storage. Premium appliances include a 48-inch Sub Zero refrigerator, Wolf appliances, double dishwasher drawers, and an oversized Villeroy & Boch farmhouse sink. The kitchen opens to a spacious family room anchored by an oversized brick fireplace and an adjacent redesigned wet bar with custom cabinetry, wine refrigerator, and bar sink. The versatile floor plan includes a main-level bedroom and full bath, ideal for guests, an office, or multigenerational living. Upstairs, the extraordinary primary suite functions as a private wing, featuring a separate retreat divided by a double-sided marble fireplace, custom walk-in closet, dual bath arrangement, and a large private balcony overlooking the rolling hills and distant lake. Three additional bedrooms are generously proportioned, including an exceptional oversized room with vaulted ceilings, French doors, custom library built-ins, and dormer window seating. Outside, a custom pool framed by stone and brick detailing creates a private setting against peaceful pastoral views, where rolling hills and grazing horses and cattle can often be seen in the distance. You will not want to miss this opportunity to have a home with the rare combination of architectural character, substantial natural materials, custom craftsmanship, flexible living spaces, and serene surroundings, all within the highly regarded Walnut Valley Unified School District
