Welcome to 17439 Donmetz Street, a newly remodeled estate located on one of the most sought-after streets in Old Granada Hills. Set on an expansive 17,400 sqft flat lot with impressive frontage and beautiful park-like grounds, this exceptional property is located within the award-winning Granada Hills Charter High School district and just moments from Old Granada Hills Village. Known for its neighborhood events, holiday celebrations, food vendors, and strong sense of community, Donmetz Street is widely considered one of the most desirable streets in the area. The grounds are truly special, featuring sprawling lawns, mature shade and fruit trees, colorful gardens, winding pathways, and multiple outdoor entertaining areas. The oversized flat lot also offers outstanding future potential for a resort-style pool, multiple ADUs, guest houses, or the creation of a private compound estate (buyer to verify with city). Inside, the single-story residence offers 4 bedrooms and 4 bathrooms, with all bedrooms providing bathroom access. Rich wood flooring, vaulted wood-beamed ceilings, a fireplace, and spacious living and dining areas create a warm and inviting atmosphere. The beautifully updated kitchen showcases quartz countertops, abundant cabinetry, built-in appliances, and a laundry room with additional pantry and storage space. The primary suite includes dual closets and a beautifully updated bathroom, while the junior primary suite is ideal for guests, extended family, or multigenerational living. Additional features include updated plumbing, recessed lighting, a long gated driveway, oversized 3-car garage, RV parking potential, dual-pane windows, central air and heat, smooth ceilings, and fully paid-off solar panels. Properties with this combination of lot size, location, community, and future potential rarely become available in Old Granada Hills.
