Sentinel stretches across the brow of a winding grade break high above the Napa Valley. This seasonal residence was conceived as an agrarian compound which draws inspiration from its agricultural roots and takes a leap forward in innovative construction and a modern expression of timber and steel craft. A gently curving gravel drive circuits the lower end of the vineyard, announcing the arrival on the property. The drive slowly straightens to align with the vineyard rows to the North and the long axis of the residential structures to the South. Three gable-end barn forms follow the ordered lines of the vineyard to one side, and on the other, hug the rock-lined edge of the forest. Flanked by main residence and guest residence on either side, the taller, middle barn structure steps back from the forest to form a broad terrace. An elegant trellised colonnade threads through the three buildings, providing shade and dappled light to the terrace – a private place for food and wine to be enjoyed overlooking the magnificent valley below.
