About This Home

As of December 2025

Situated on a private +/-5.5 acre parcel on Sonoma's desirable Eastside, 3 bedroom/3.5 bath single level recently remodeled contemporary farmhouse-style home. Light and bright interiors with walls of glass looking out to rolling hills, majestic Oaks, and large in-ground swimming pool. White Oak floors, double height greenroom, dream kitchen with high end appliances, and fireplace. U-shape residence with primary bedroom at one end and guest bedroom wing at the other. 5 bedroom septic system installed allows for 2 more bedrooms so perhaps next owner will want an ADU, guesthouse, etc.
