Sonoma's Eastside, behind the gates of The Ranch, where the view does the talking. Some homes you tour. This one you feel the moment the valley opens up in front of you. Set on more than 6.5 private acres in Sonoma's coveted gated Eastside, this architect-designed contemporary frames panoramic views across the vineyards and valley floor to the Bay and the San Francisco skyline beyond. Walls of glass pull that view into nearly every room, and a recent renovation by an internationally recognized interior designer brings a confident, current sensibility to spaces built around light, stone, and the landscape itself. The home is designed in distinct levels, and that's the point. Each living zone has its own privacy and purpose: a serene primary retreat with a private balcony, separate guest quarters that give visitors their own world, and a dedicated office and loft for the way people actually live and work today. Open-beam ceilings, two fireplaces, hardwood floors, and a chef's kitchen with high-end appliances anchor the main living spaces, nearly all of them opening to the outdoors. A separate three-car garage adds everyday ease and storage you rarely find at this elevation. Below, a wine cellar built from stone quarried on the property itself speaks to what makes this place rare: it is genuinely of its land. Majestic oaks, Japanese maples, hand-laid stone walls, and gently terraced topography create a setting no flat lot can replicate, usable, sculpted, and completely private. Mature gardens thrive on a smart, timed irrigation system throughout, and a large fenced dog run sits just off the house for easy access. A pool has already been designed for the property by a local Sonoma designer, so the vision for outdoor living is in place and ready to bring to life. Fire insurance is secured and in place. Just minutes to the historic Sonoma Plaza, its restaurants, and world-class wineries. Newly priced and unlike anything else on the market. This is the one the others are compared to.
