Nestled in the highly sought-after Altadena Country Club neighborhood, just steps from the historic Altadena Golf Course, there stands this stunning one-story Colonial Revival residence. Built in 1917, the home sits majestically on an expansive, beautifully landscaped lot spanning 13,860 square feet. This charming home underwent a comprehensive remodel in 2018, executed with a thoughtful eye toward enhancing and preserving its original architectural character. You'll find the warmth of hardwood floors, large baseboards, and elegant crown moldings. Large, plentiful windows and multiple French doors flood the interior with natural light and fresh air that define the home's open, airy aesthetic.The heart of the home features a grand Living Room and a Formal Dining Room, both designed for entertaining. French doors provide a seamless transition from these formal spaces to a newly expanded outdoor terrace. The 1,200 square foot Bluestone patio is ideal for hosting intimate gatherings or large celebrations.The home boasts four generous bedrooms. The Primary Bedroom Suite is a private sanctuary, featuring an en-suite bath with Carrera marble countertops, gleaming polished nickel fixtures, tub, marble stall shower, heated marble tile floor, separate toilet room, and a spacious walk-in closet. Two additional bedrooms access the hall bathroom. The fourth bedroom, off the kitchen, has a private bathroom and can be closed off as its own suite. The centerpiece of daily life is the spacious gourmet Kitchen with Caesarstone counters and a striking center island measuring over 13 feet long. The Kitchen is equipped with top-of-the-line Sub-Zero and Wolf appliances and opens to the Breakfast Area and Family Room. A separate laundry room with a stainless-steel laundry sink and abundant custom cabinetry adjoins this space. The property features a gated driveway leading to a two-car garage. There is an attached permitted accessory space, which, if combined with the garage, has the potential for an ADU conversion of over 780 SF. The modern infrastructure boasts new HVAC equipment, a new tankless water heater, a whole-house water conditioning system, and a grid-connected solar power system paired with two Tesla Powerwall 2 batteries.With 2,990 square feet in the main residence and an additional 280 square feet in the separate accessory space, 1351 Sonoma offers a rare combination of historic elegance, luxurious amenities, and modern practicality.
