Tucked away on a 12.4-acre picturesque plot in west Petaluma, lies an Old World style estate that is both luxurious and eco-conscious.

The two-home compound features a four-bedroom, five-bathroom 3,955-square-foot main residence and a detached 638-square-foot guesthouse.

Designed by Plath and Company architect David Buergler, the estate features a LEED Platinum certification – the highest standard in sustainable building.

The home takes the motto of “reduce, reuse, recycle” to an entirely different level with interiors that feature 100-year-old wood beam ceilings, salvaged barn wood floors, recycled granite counters and reclaimed concrete floor tiles. On the outside of the home are lush gardens and plenty of room for a trail system on the sprawling 12.4-acre estate. Energy at the villa comes courtesy of a solar energy system and water comes from a well and 25,000-gallon rainwater collection tank.

The compound is so eco-conscious you might forget about the high-end amenities. The home features a massive gourmet kitchen with a fireplace at one end and a gigantic island work space at the other. The four spacious bedrooms are each serviced by their own bathrooms and the central living space features breathtaking views of San Antonio Valley.
