4004 Snowgoose St, Simi Valley, CA 93065

Nestled on over 3 acres in Simi Valley’s exclusive Big Sky community, this exceptional single-story custom estate sits on one of a handful of custom lots—a rare combination of private acreage and refined design. The main residence features 4 bedrooms/5 baths, with en-suite bathrooms in every bedroom, plus custom walk-in closets and ceiling fans. Rich hardwood floors, vaulted ceilings, and crown molding elevate the open concept that flows from the formal dining room and butler’s pantry to the expansive living room with a stacked-stone fireplace and tri-fold doors that blur indoor/outdoor living. The chef’s kitchen showcases high-end appliances, a walk-in pantry, farmhouse sink, oversized island, and custom cabinetry. A versatile bonus room with fireplace is perfect for an office or guest space, and the mudroom/laundry offers built-ins and a sink. Outdoors, enjoy a resort pool & spa, full vegetable/herb garden, and multiple producing fruit trees—all backing to open space with no rear neighbors. Above the detached 3-car garage is a beautifully upgraded true ADU (1 bed/1 bath) with a full kitchen, in-unit laundry, A/C, tankless water heater, and sweeping views—ideal for guests, older kids, or rental income. A convenient full bathroom inside the garage opens toward the backyard/pool area—perfect for swimmers and guests so no one has to track water through the house. With over 3 acres of usable land offering outstanding additional ADU potential, and a location that feels tucked away yet minutes to shopping, dining, and freeway access, this is a rare opportunity to own one of Big Sky’s most desirable custom homes.
