In a coastal enclave where developable land has all but disappeared and architectural heritage is measured in decades rather than centuries, the compound at 660/670 Buena Vista Drive represents something the Montecito market rarely produces: an irreplaceable original.

Listed at $18,500,000 and offered by Marsha Kotlyar of Berkshire Hathaway HomeServices California Properties, the property is one of the last intact Provincial Garden compounds from the 1933 era remaining in Montecito’s celebrated Golden Quadrangle — a neighborhood that has drawn the world’s most discerning buyers to the Santa Barbara coast and seen its global profile rise sharply in recent years. The estate spans 3.41 acres across two parcels, encompassing an approximately 6,000 square foot main residence, two fully independent historic guest houses, and grounds designed by noted landscape architect Sydney Baumgartner.
“What makes this property significant isn’t any single feature — it’s the totality,” says Kotlyar, whose 23-year career on the Santa Barbara coast has produced more than $2 billion in sales and placed her consistently in the top half of one percent of the BHHS global network. “The scale, the provenance, the Baumgartner landscape, the location within the Golden Quadrangle — assembled together on 3.41 acres, this is the kind of compound that does not come to market. And when it does, it does not come back.”
The estate was originally constructed in 1933 and meticulously rebuilt in 1999, preserving the compound’s defining architectural character — smooth stucco, wrought iron detailing, custom handcrafted tile, arched doorways, and Andalusian courtyards — while delivering the infrastructure and systems a contemporary buyer requires. Three gated entries serve the property’s two parcels independently, accommodating multi-generational use or the possibility of two distinct primary residences on a single contiguous holding.
The main residence unfolds around a series of connected courtyards and indoor-outdoor living spaces anchored by panoramic ocean and mountain views. A French countryside-inspired kitchen and family room open on both sides to alfresco entertaining terraces, while the formal living room’s symmetrically placed French doors frame an unobstructed ocean horizon. The Rosemary Residence guest house — reached by its own private drive — offers a full kitchen, living room, bedroom, and central courtyard. The Lavender Guest House provides an additional independent living suite tucked deep within the grounds.
Baumgartner’s landscape, considered among his most accomplished works in the region, layers prolific orchards, mature palms, manicured gardens, a putting green, and a gazebo across terrain that rewards extended exploration. In a market where buyers are increasingly acquiring Montecito properties for their land as much as their structures, the Baumgartner provenance alone distinguishes this offering.
Montecito’s ultra-luxury segment — properties listed above $10 million — has seen sustained demand from domestic and international buyers seeking privacy, natural beauty, and proximity to both Los Angeles and San Francisco. Inventory at the compound level, particularly properties with verified architectural heritage and multi-parcel configurations, remains critically constrained.
670 Buena Vista Drive is listed at $18,500,000. For media inquiries, photography, or to arrange a private tour, contact Marsha Kotlyar at 805-565-4014 or home@mkgroupmontecito.com. Additional information is available at www.MontecitoFineEstates.com.
