The Boone House is a rare Dutch Colonial revival example in San Ramon, and the David Glass House represents 1870s Italianate residential architecture. The outbuildings show changes in farm building technology, such as the move to corrugated metal for fire resistance.","narrative":"Forest Home Farms is a 16-acre remnant of a farm established in 1850 in San Ramon, once covering 710 acres across the San Ramon Valley. The surviving district holds 17 contributing buildings and 3 structures. Its centerpiece is the Boone House, a Dutch Colonial revival home built in 1900 with a gambrel roof and full-width classical porch, attached to an older Gothic revival wing that may have been the original farmhouse. The David Glass House, an Italianate home from the 1870s, was moved to the property in 1998. Surrounding them are barns, sheds, a meat locker, pergolas, a grotto and walnut processing buildings. The farm is significant for showing how local agriculture changed, particularly the family's walnut operation in the late 1930s and the growing use of corrugated metal to reduce fire risk. Rehabilitation work is under way to restore the landscape and buildings for museum and meeting use.","period_of_significance":null,"architect_builder":null,"architectural_style":"Dutch Colonial revival (Boone House, with a vernacular Gothic revival north wing); Italianate Victorian (Glass House); vernacular farm buildings","criteria":[],"status_note":"Rehabilitation of buildings and landscape is underway or proposed.
