A rare, fully reimagined designer home in Orange County--truly turnkey and custom rebuilt to perfection. Located in the prestigious Montbury on the Hill community in North Lake Forest, this stunning residence was transformed by a Newport Beach-based professional designer focused on luxury, functionality, and signature style. For buyers tired of cookie-cutter tract homes, this is a custom alternative that stands out in every way. Among its most exceptional features are dual primary suites--one on each level--ideal for multigenerational living, guest flexibility, or a dedicated office. Natural light floods the home through soaring ceilings and expansive windows, creating a warm, open, and elevated atmosphere. The chef's kitchen features GE Cafe appliances, Taj Mahal quartz countertops, custom cabinetry, and integrated LED light strips that extend into the closets and staircase--every inch thoughtfully crafted. A spacious family room offers a custom media wall, built-ins, and an open lounge with a transparent glass wine display. The downstairs suite includes sliding-door access to the backyard, a spa-style bath with a freestanding tub, dual rain-head shower, double vanities, and a large walk-in closet that can double as a dressing room or office. Upstairs, a second primary suite offers a fireplace, full bath, and large sitting area. Two additional bedrooms feature custom closets and share a dual-sink bath. Upgrades include new PEX repiping, dual-pane energy-efficient windows and sliders, smart LED lighting with dimmers, a modern tempered glass staircase, new flooring, new doors and hardware, fully customized closets with lighting, and a brand-new roof currently being installed. Two fireplaces--one in the living room and one in the upstairs suite--add warmth and charm. The landscaped backyard features a covered patio, pool, and expansive lawn ideal for entertaining. A 3-car garage, extended driveway, and separate laundry room offer everyday convenience. The community includes tennis and pickleball courts, scenic equestrian and hiking trails, and well-maintained parks. Conveniently located near the 241 Toll Road and I-5 freeway access, and surrounded by well-rated public and private schools. Renovated to the highest standards, this home has not been occupied since its transformation--show with confidence; there's truly nothing else like it on the market.
