This remodeled 3,406 sq. ft. estate offers a rare entry-point into "The Country," paired with enrollment in the top-rated Walnut Valley Unified School District (Evergreen Elementary, Chaparral Middle, and Diamond Bar High). Inside, expansive windows frame breathtaking, unobstructed mountain vistas. The remodeled chef's kitchen features granite countertops and stainless steel appliances, while the family room boasts rustic beam ceilings. The private master suite offers direct backyard access and a luxurious bath with a separate shower, soaking tub, and granite-topped dual sinks. The unique split-level layout includes a massive lower-level bonus room with a rock fireplace, wet bar, and storage—perfect as a private executive office or media room. Outside, an upgraded deck built along the canyon slope provides a front-row seat to spectacular mountain views. Complete with fragrant fruit trees and side-yard RV parking, this home perfectly blends functionality with hillside serenity.
