Sausalito Residence: This new, 5,350 sf modern hillside home was designed in response to its unique site with magnificent views and the needs of a growing family. The home’s aesthetic is inspired by the Second Bay Region Tradition and expressed through its exposed structure and use of simple, natural materials such as cedar siding, steel structural elements, stone, pigmented concrete, and copper. The multi-level design allows for a series of experiences as one proceeds down varied garden steps into the backyard. Photo: Pfau Long Architecture

The project includes a 600 sf addition, expanding on the concept of transparency that characterized the original home. Relying on the simple clarity of its design, all of the structure is exposed, including wood beams, structural steel, custom steel brackets, and a “floating” steel stair. The residence’s transparency creates the illusion of boundless space. Photo: Matthew Millman
