Historic Winery, Mansion Serves as Basis for Ontario Mixed-Use Project

Formerly one of the largest wineries in California, the Guasti estate in Ontario is awaiting an ambitious redevelopment project later this year.

There are no plans to bulldoze the historic property. Instead, most of the buildings will be preserved and incorporated into a mixed-use commercial development featuring between 500,000 square feet and 1 million square feet of vertical product, including entertainment, restaurants, retail, office, multifamily residential, hotel and office space.
