Inspired by a lifestyle...

This significant legacy Sonoma County ranch retreat sits amongst the foothills of Sonoma Mountain on approximately 350+/- acres of unparalleled beauty and consummate style. The estate offers peaceful privacy, carefree stylish living, and breathtaking mountain and sunset vistas.  Inspired by a lifestyle, the ranch carries the trademark of modern California living…inventive, inspiring and elegantly informal.

Substantially renovated and redesigned in a collaborative fusion of classic Spanish Colonial architecture and modern design elements, this remarkable property is simply unmatched in excellence.  Stunning main residence, private guest house and detached 3-car garage cluster around a circular courtyard with gated entrance.

Sumptuous interiors, rich textures and organic elements contrast with broad hallways, curved arcades, smooth stucco and walls of glass to create a soft contemporary environment.  Interior and exterior space is merged through a dramatic open-air corridor that connects symmetrical wings of the house and flows through to the pool terrace and verandas.

Designed by architect Mark de Reus to showcase a sense of place and timeless aesthetic.  Resort style amenities…luxurious pool and limestone terrace, expansive loggia, intimate verandas, fireside al fresco dining, lighted tennis & sport court with viewing pavilion, expansive lawns, pristine ponds, meandering paths and manicured gardens, stone walls and extensive patios. A detached 1BR/1BA guest house, with views overlooking the upper lake, provides a private respite for guests.  Additionally, the 2BR caretaker home was recently renovated and offers comfortable on-site housing for ranch manager or staff.  For the equestrian, an impressive center-aisle six-stall barn, arena, pastures and trails to explore. Explore the expansive meadows, seasonal creeks and oak-studded hills. Hike, ride, kayak, play tennis or go fishing without leaving home.

Small town with big class.

The lifestyle and amenities of this vibrant small town attracts residents who are drawn to the small-town atmosphere, quiet sophistication and ideal centric location.  With commutable viability to San Francisco and ease of access to Northern California’s vast recreational resources.

According to Forbes Travel Guide, 2017 Petaluma is “quickly becoming the wine country’s hottest new region”.  That prediction was realized when the Petaluma Gap AVA became Sonoma County’s newest viticultural designate in December 2017.  Along with popular wine industry events, an emerging nightlife, popular local breweries and a cool vibe to downtown shops and riverfront festivals has put Petaluma squarely on the map.
