Outside, in addition to three deck areas, the home features a sun-drenched raised patio.  Imagine morning coffee with hummingbirds in the nearby wisteria or a sunset glass of wine with the neighbors.  The yard’s gardens feature a mix of native oaks and mature trees as well as California chapparal.  A sunny garden area with raised beds accommodates summer produce with fencing to keep it safe from deer.
