Set on a steep Tiburon hillside overlooking the Bay and Belvedere Island, this project re imagines a historic structure once used by the Northern Pacific Railroad to store train records. The design honors the site’s working past through a modern architectural language rooted in material honesty — weathered wood, textured unit pavers, corten steel, and board-formed concrete echo the vernacular utility of the original barn while introducing refined, contemporary forms. Landscape interventions navigate the tight slope with terraced platforms, permeable pathways, and sculptural planting that connect structure and terrain. A fire-adapted, drought-tolerant plant palette — rich in resilient California natives — grounds the architecture in its climate, elevating the design with an understated, ecological elegance that recalls the spirit of the site’s origin.
