Not everyone can spot a unicorn. Can you?

During the course of our lifetime, a small number of talented and hard working Bay Area visionaries have created unique products and services that have made all of our lives so much better. And in so doing, those visionaries have created enormous wealth for themselves, and for their investors.
Many of those successful Bay Area based Financiers, Entrepreneurs, and Entertainers have their third or fourth homes in distant states like Montana, Wyoming, or Colorado, and some go as far as Patagonia, or even New Zealand’s South Island, just to have an “off-the-grid escape” for themselves, and for those they love. It’s not uncommon that their ranch houses, barns, and guest homes are on large parcels of land that are measured in the hundreds, or even thousands of acres. And the most astute of those visionaries have acquired private land that is surrounded by tens of thousands of acres of open, undeveloped public land, where they can explore endlessly, as they stand in awe of nature, and in celebration of life; in all its glory.
Which one of those visionaries will recognize the fact that there is such a plot of land, right here in the Bay Area, less than 12 miles north of the Golden Gate Bridge?
The King Mountain Estate is a privately held 140+ acre parcel of land, with vested development rights, allowing for the construction of an enormous compound, adjoining thousands upon thousands of acres of public open spaces that can be accessed directly from the privately held parcel. And while The King Mountain Estate enjoys access to public utilities, it also has its own source of water, and is perfectly suited to create sufficient levels of solar energy to comfortably power the future compound, allowing for an off-the-grid lifestyle that simply cannot be replicated anywhere else in the Bay Area.
This ridge-top parcel offers its next owner the once-in-a-lifetime opportunity to build a legacy residential compound of unimaginable privacy, beauty, and sheer size, in southern, unincorporated, Marin County, on a panoramic view site, at the edge of civilization, yet in the midst of Nature’s Paradise. The 30+ acre building envelope, within the 140+ acre parcel, is on the ridge-line atop of King Mountain. As such, it enjoys 360-degree views of the city of San Francisco, the East Bay, and Marin, as well as unobstructed views of the Bay, Bridges, and of course, Mt. Tamalpais; plus many of the Bay Area’s most prominent peaks, and surrounding open spaces.
So why buy a gated estate in Ross or Kentfield on an acre or two, and go through the time, effort, and expense of remodeling someone else’s dream home, when you can build your own, panoramic-view, dream compound, atop King Mountain, on your own 140+ acre parcel, adjoining hundreds of thousands of acres of open space?
So many talented visionaries dream of creating Unicorns…
One of those successful visionaries will surely see that King Mountain is the Bay Area’s best Real Estate equivalent.
Incredibly, this completely secluded ridge-top paradise is just a few minutes away from shops and restaurants, just four miles from Highway 101, and less than 20 minutes from the Golden Gate Bridge. And yet, it is a million miles away from city living.
In addition to Redwood Groves, Madrones, Oaks, and other native Flora and Fauna, the land enjoys direct access to hundreds of miles of hiking and riding trails, and direct access to thousands upon thousands of acres of open space.
The King Mountain Estate is fully vested and entitled, with approvals for the construction of a legacy compound in excess of 27,500 square feet, that includes a main residence, guest residence, caretaker’s home and other auxiliary buildings, as well as a large pond, access roads and pathways, vineyards, orchards, horse corrals, and elaborate water features. When complete, the King Mountain Estate will be like no other residential compound in the Bay Area.
There are thousands of view homes in the Bay Area; hundreds of view homes in prestigious neighborhoods; dozens and dozens of private view estates that are owned by the most celebrated, successful, and affluent creative minds of our time: But there is only one King Mountain.
No other estate property in the Bay Area compares. It is truly the last Unicorn.

Marin County
KENTFIELD AND LARKSPUR
∎
About Kentfield
Some of the most beautiful properties in Marin can be found in Kentfield, a quiet community of spacious older homes sited on large, lushly landscaped parcels. One of the town's meeting points of this upscale residential community is the Woodlands Market, a unique gourmet grocery store, bakery, wine bar, and cafe. For more than 20 years, Woodlands Market has been the place where residents get their fill of local news and events while filling their grocery cart.
Public schools in Kentfield are among the best in Marin. Bacich Elementary, with one teacher for every twelve students, and Kent Middle School, with an API of 890, are in the top ten percent of schools in California. Kentfield is also home to Marin Catholic High School, the largest private school in Marin County, and the College of Marin, a two year community college with a strong local presence and an excellent reputation as a feeder to the University of California system. College of Marin offers adult classes for the public, and a vibrant performing arts program of theater, vocal, and classical music. The frequent public performances provide neighborhood residents with access to the cultural arts not normally found in a town of 7,000.
About Larkspur
One of the most spectacular features of houses in Larkspur is the scenery surrounding them. Redwoods rule in Larkspur. In Baltimore and Madrone Canyons, giant redwoods grow straight out of the roadway, while the streets gently curve their way around these massive trees. Tucked away under the redwoods beneath Mount Tam, Larkspur boasts world-class restaurants, including the Lark Creek Inn Tavern. The town’s main street, Magnolia Avenue, is a vibrant destination for food lovers who frequent Picco, Cafe Rulli, and the Left Bank Brasserie. The Lark Theater, also on Magnolia, has been recently restored to its art deco glory by a community effort that supports first run films and live music performances. The Larkspur/Corte Madera path runs a few blocks parallel to Magnolia, on a former railroad right-of-way, and is popular with families, dog walkers, and bikers on their way to Point Reyes. Larkspur and the neighboring town of Corte Madera share one of the best school districts in the state, with Redwood High School consistently achieving API scores in the high 880s.
