About This Home
Situated minutes to Calistoga's world-class spas, wineries, and culinary destinations, 8495 Franz Valley School Road is an unparalleled expression of contemporary refinement, privacy, and natural beautya modern sanctuary at the intersection of architecture and landscape. Designed by the renowned Signum Architecture and brought to life by Fairweather and Associates in 2020, this private retreat redefines modern luxury. A gated entrance and short drive unveil a home described as having a strong sense of horizontality and a palette of wood-on-wood, punctuated with metal.'' Durable materials of concrete, stained cedar, aluminum-framed expanses of glass, and Japanese shou sugi ban siding (insect and fire resistant) unify beneath a sleek parapet roof. Walls of glass disappear to dissolve the boundary between indoors and out and lead to an inviting heated pool w/ spa and an outdoor kitchen with expansive views. A private tennis court adds to the resort-style living. The layout is thoughtfully attuned to the Terremoto/Alain Peauroi masterful landscape design complementing the architecture's geometric precision. In keeping with the home's open and transparent ethos, a carport replaces the traditional garage, ensuring the architecture remains unobtrusive and deeply connected to the land.
