It's hard to imagine that this tree-filled parcel of land in scenic Sonoma County was once a barren landscape. The 9.5-acre property on the market for $1.2 million in Glen Ellen, CA, was lovingly nurtured by the sellers, who bought the land about 40 years ago.

"The owners did all the work, physically built, and created this property over the years," listing agent Michael Hedley says.

Over four decades, what was once just dirt became "an oasis," Hedley adds. An oasis with its own Evian-worthy natural spring, a garden, and numerous fruit trees. Garden of Eden, anyone?

The property comes with a 500-square-foot manufactured home that the owners customized with redwood siding and a delightful porch. It has two bedrooms and one bathroom.

The property is filled with mature trees, including redwoods, oaks, and Japanese maples, all planted by the owners years ago. There's also an on-site nursery where Japanese maples are cultivated and sold around the state.

Dotting the lush landscape are a footbridge, stone paths, and lounging areas. There's also a fenced-in tiered garden and a steel-frame and adobe-block workshop and office.

The large property could accommodate another residence, Hedley says. This plateau overlooking the Sonoma Mountain range and a nearby vineyard is "quite a magical place. It's kind of breathtaking."

The property could also be a weekend retreat for a San Francisco Bay Area buyer. "It's the ultimate getaway," Hedley says. "Once you get down here, you're truly in your own world."

The locale is about 1.5 hours from San Francisco and 30 minutes from the Sonoma Plaza for shopping and dining. Be sure to make a stop for groceries -- once you get here, we're guessing you won't want to leave for possibly another 40 years.
