This never-lived-in, 4-bedroom, 3.5-bathroom, three-story home offers 2,429 square feet of thoughtfully designed living space with luxury finishes throughout—and no carpet! This energy-conscious home features owned solar panels, wall batteries, an EV charger, and a Halo-5 whole-home water filtration system. Additional highlights include luxury vinyl flooring, designer window coverings, city and mountain views, an outdoor kitchen, and one of the largest yards in the neighborhood. FIRST FLOOR: Designed with flexibility in mind, the private bedroom and full bathroom can function as a guest suite, home office, gym, in-law suite, or multigenerational living space. The area can be closed off from the main residence and offers the potential for an attached junior ADU-style setup. It includes direct garage access, a washer/dryer, sink, and private access to the backyard and full outdoor kitchen. The outdoor kitchen features a built-in BBQ, 2-burner cooktop, mini refrigerator, and microwave. A spacious patio with luxury pavers and low-maintenance landscaping creates a sunny and inviting outdoor retreat. SECOND FLOOR: The heart of the home features a spacious open-concept great room with a beautifully appointed luxury kitchen and an impressive 23-foot-wide covered patio. The kitchen showcases white shaker cabinetry, white quartz countertops, stainless-steel appliances, an electric induction cooktop, smart refrigerator, reach-in pantry, and a large island with stainless-steel sink and seating for up to four. THIRD FLOOR: Three additional bedrooms, two full bathrooms, and a dedicated laundry room provide plenty of space and privacy. The spacious primary suite features a private balcony, two walk-in closets, a luxurious freestanding soaking tub, and a walk-in shower. The formal laundry room includes a brand-new washer and dryer set. And yes—there are two laundry areas, one serving each living space. The attached garage includes a covered driveway, providing the ability to accommodate two additional vehicles in front of the home. Outside, enjoy one of the neighborhood's largest yards, complemented by views of San Marcos city lights and surrounding mountains. The Hill District in North City is a thoughtfully planned community featuring innovative architecture, modern amenities, and sustainability-focused design. Planned and developing amenities include a luxury community center, pool, sports courts, and future parks. Conveniently located with immediate freeway access and close to restaurants, shopping, and everyday conveniences.
