On-site Amenities


The development offers extensive opportunities to its residents. 

The 1.25-acre farm and orchard function as an urban homestead where residents can grow fruits and vegetables. In addition, an energy-efficient, production greenhouse provides indoor space to encourage year-round activity.  The farm area is a natural link to the town of Sonoma and its residents through sales at a farm stand and direct arrangements with local restaurants. 

The therapy pool and community deck area are a focal point of activity year-round.
