High-powered executives envisioned a Napa Valley getaway for family and friends to gather. Fascinated with the architecture of Umbria, Italy, the homeowners worked with their design team to create an authentic environment using chestnut timbers, antique roof tiles, antique floor tiles and stone sourced and imported from Italy, with many other elements that were crafted abroad. The trompe l’oeil panels in the home theater are based on the 18th century frescoes of an Italian villa. Photography by Blake Manosh
