An unparalleled opportunity awaits in Ross's premier location, on a mostly level 1-acre south-facing parcel in the coveted flats. Reminiscent of an East Coast estate, this gem is designed to enjoy Marin's indoor-outdoor lifestyle. Great scale living spaces open to sweeping level lawns, bluestone patios with outdoor fireplace, and sparkling pool. The Michael Yandle-designed grounds are a masterpiece of privacy, multi-season blooms, and stately trees. A 'down to the studs' rebuild/expansion led by John Wheatman created a light-filled, timeless shingle style residence with gracious porches, vaulted ceilings, art walls, custom millwork, wide plank hardwood floors, and designer lighting. The heart of the home is the recently remodeled kitchen and family room, where a retracting glass wall opens to the outdoor oasis. The Sandra Bird-designed chef's kitchen boasts white quartzite counters, custom metal hood, and professional-grade appliances. Impeccable floor plan includes a library and a recreation room leading to the back yard. Primary suite features spa-like marble bath and private terrace. All bedrooms in the main house enjoy ensuite baths. Guest house with kitchenette and full bath, gym, 3-car garage. Just blocks to acclaimed K-8 Ross School, Branson School, & hiking/biking trails!
