This property, near Calistoga, offers expansive views. The surrounding terrain falls away quickly, adding drama to the setting. Each of the spaces in the main house capture the panorama by means of the plan, which alternates between indoor and outdoor rooms. The swimming pool and spa, at the heart of the site, unifies the composition between structures. The guest house is carefully sited so that like the main house, all the rooms enjoy uninterrupted site lines.
