Description
For the first time in 35 years, this premier Mill Valley property, coveted by would-be buyers but held dear by its owners, is available for sale. Mature oaks and pines surround this quiet retreat and an ascent through the gate and up the private drive reveals a magnificent English Manor home on almost an acre of sun-drenched hilltop. “Scattered Oaks,” as the property is called, is grand and welcoming, yet secluded and convenient to town. This classic 4 bedroom, 3.5 bath home is beautifully designed and well located in the prestigious Mill Valley Country Club neighborhood. Its 360 degree views span the San Francisco Bay, the city skyline, and Mount Tamalpais. Outdoor enthusiasts will be pleased to find trailheads right up the road, birds in every tree, and plenty of level land for playgrounds and gardens. Originally built in 1929 by Dorothy Monroe, the house was extensively rebuilt in 1975, boasting approximately 3,147 sq ft. of living space and another approximately 1,000 feet of attic. The rooms are light and spacious and everyone has a spectacular view. At the main entrance, a gracious two story foyer flows into the living room, family room and kitchen and a grand staircase leads to the upper level. Upstairs, the master bedroom has a marble fireplace, a walk-in closet, and a balcony that overlooks San Francisco and the bay. Adjacent to the master bedroom is a lovely, library/private study. Off the library a tiled solarium opens to the guest bedroom and guest bath. The main level has a large living room with vaulted beamed ceiling, a stone fireplace, and French doors leading both to the front deck and the back yard. The front yard overlooks San Francisco and the back yard and back deck look west to Mt. Tam sunsets. Just off the living room is a formal dining room filled with similar views. The eat-in kitchen is large and has a gas stove, newer appliances, and a perfect pantry. The kitchen flows into an informal dining room and a family room with a tile fireplace. There are two more spacious bedrooms on this level with an additional bathroom and guest bathroom. The main level features hardwood floors throughout. The lower level includes a two car garage and just off the garage is a bonus room with lots of storage. The home hums with the energy of children and grandchildren raised here, books written here, elegant parties that filled the halls and warm, fireside family holidays. Your key to the magic of historic Mill Valley is at 523 Hillside Avenue.
